Surfaces & Interfaces

Surfaces and Interfaces: Surface of a material is the host to a number of activities including chemical, optical, electrical, electronic and magnetic interactions. This is because, atoms on the surface encounter a different environment than that of their bulk counterparts. Atoms inside the bulk of a material are surrounded by similar/identical geometric configurations; on the other hand, atoms on the surface, are being attached to the material on one side by either chemical/physical bonding, the other side is free. The absence of neighbouring atoms on one side results in an imbalance in the force experienced by the surface atoms. In such a scenario, the surface atoms try to find an equilibrium structure which is different from that of bulk. This could happen in two ways: relaxation and reconstruction.

Normally in metals, in-plane atoms on the surface try to increase their inter atomic distance, and also interlayer spacing (relaxation). These changes in inter-atomic and inter-layer distances decrease and tend towards standard bulk values as one move deeper inside the materials (bulk). But in some materials, normally in semiconductors, atoms on the surface assume entirely different structure from that of the bulk, to compensate for the absence of neighboring atoms. This is called reconstruction.

In essence, there is a lot of activity happening on the surface, and if one can increase the number of atoms on the surface compared to bulk, activity of a material increases manifold which leads to drastic changes in chemical, thermal, electrical and many other physical properties of a material. This is what exactly happens in nano materials!!!

Changes in properties can largely be attributed to change in surface to volume ratio as more and more number of atoms occupy the surface and more often than not this and the resulting  quantum size effects makes these nanoparticles more active  to its surrounding environment. Most of the research going on now-a-days is to modify and tune these properties so that it could be useful to mankind via  medical, energy related and catalytic applications to name a few.

Another scenario is when the surface of material is attached to another material. The resulting interface also throws up a lot of interesting physical phenomena wherein, atom on one surface tries to bond with a different atom leading to interface relaxation, epitaxial growth and even formation of defects. So, fundamentally, surfaces and interfaces of materials are one of the most exciting area of physics and the detailed structural and chemical study of such surfaces/interfaces would help us in understanding a host of material properties which are important in energy, environment related applications.

Three of the major areas being looked upon in this lab are multilayer thin films for energy applications, embedded nanostructures in insulating matrices for opto-electronic applications, and tuning nanoparticle orientations to increase their surface activities.

Study of oriented multilayer thin films on crystalline substrates:

When a system comprises of surfaces and interfaces, there are lot of potential activities happening at the interfaces as well on the surface (as explained in the figure below). In such cases orientation of the substrate plays a very important role.

For example, when gold thin film is deposited on a Si(110) substrate, the gold-silicon interface tries to arrive at a minimum energy configuration which influences the final morphology of the thin film itself. Moreover, if the system is subjected to higher energy (heating), interface mixing takes place, leading to drastic changes in surface morphology which is hugely influenced by the orientation of the substrate. Studying such interfaces involving Semiconductor/Metal Oxide/Metal thin films is one of the projects being undertaken in this lab. Here, selected metal oxide thin films is being deposited using various Physical Vapour Deposition techniques (including Thermal, Pulsed Laser and Magnetron sputtering deposition) and then analyze whether orientation of the deposited thin film has any effect on its optical, chemical and structural properties compared to randomly deposited thin films, right down to nano/atomic level.

Embedded nanostructures:

Light absorption/conversion efficiency of semiconductor nanostructures mainly depend on five major criteria. First and the most obvious one will be size of the nanoclusters. Apart from that, embedding matrix, amorphous/crystalline nature of the nanostructures, presence of surface and interface states, shape of the nanostructures also have substantial effect on light absorption property. Si and Ge quantum dots (QD) are the major elemental species being explored; especially Ge QDs have received renewed interest in recent times because of larger bulk absorption coefficient, larger exciton Bohr radius, which makes band gap tuning easier, and lower.


Embedded metal nanostructures in insulating matrix (Microscopy and Microanalysis 18 (S2), 382-383, Physical Chemistry Chemical Physics 15 (12), 4291, NIM B307 (2013) 273)

synthesis temperature among others. In this project, the objective is to study the matrix-QD interface, effect of inter QD distance and process of agglomeration of Ge ions into Ge nanocrystallites at high temperatures in-situ. Low energy elemental ions will be implanted in dielectric matrices. Process of incident ions agglomerating into amorphous/crystalline nanostructures and then the structural and chemical properties of Ge/SiO2 and Ge/Si3N4 interface shall be studied in detail.

Oriented Nanocrystals:

Apart from reducing the size of a material to increase number of surface atoms, crystalline orientation of a nanostructure also plays an important role in defining its physical properties. It is well known that the surface activity of a nanocrystal essentially involves interaction of surface atoms with surroundings. The ease with which, making and breaking of chemical bonds that take place between the surface atoms and the surrounding environment depends on surface crystalline orientation. This is because, number of reactive sites on the surface (ex: dangling bonds) varies with crystalline orientation. So, apart from reducing the size of the nanoparticles, the morphology of nanoparticles can be tuned. This leads to the exposure of the most active surfaces. The main aims of this project are in identifying specific metal-oxide systems and tune their shapes to increase their surface activity and thereby catalytic efficiency.


Investigating the surface atom dynamics and cationic reconstruction (ACS Nano 6 (2012) 421, Adv Func Mater  21 (2011) 1971, Journal of Physics: Conference Series 371 (1), 012007)

Endotaxial nanostructures by low energy ion implantation:

Coherently embedded metal nanostructures (endotaxial) are known to have potential applications concerning to the areas of plasmonics, optoelectronics and thermoelectronics. Incorporating appropriate concentrations of metal atoms into crystalline silicon is critical for these applications. So, choosing proper dose of low energy ions, instead of a depositing thin film as a source of metal atoms, helps in avoiding surplus concentration of metal atoms that diffuses into the silicon crystal. In this work, 30 keV silver negative ions are implanted into a SiOx/Si(100) at two different fluences. Embedded silver nanostructures have been characterized by using planar and cross-sectional TEM (XTEM) analysis.
