Nanomanufacturing

Our focus is to address some of the major challenges of nanomanufacturing by combining large scale bottom-up and top down approaches, in situ characterizations and make devices. We use vapor phase methods to achieve controlled growth of aligned CNTs, Graphene, MoS2, VO2 nanostructures, thin films and hetrostructures.

Nanomechanics

Mechanical properties of materials at nanoscale especially properties of surfaces and small structures are important and attractive to use nanomaterials for various applications. We use in-situ nanoindentation for investigating temperature dependent mechanical, tribological properties at very low loads. We also explore how mechanical force modulates the electrical properties of materials at nanoscale by contact resistance measurements.

Smart materials

Smart materials such as shape memory alloys, VO2 that undergo phase transition are attractivefor developing actuator, sensor, electrical devices and portable cooling applications.We are interested in both fundamental aspects triggering phase transition by different external stimuli and making novel hybrid smart structures.

Electron Microscopy

Electron microscopy is essential tool for nanotechnology and nanomanufacturing. We use FESEM along with e-beam lithography for making nonpatterns and devices. Detailed microstructural and crystallographic investigations of developed materials and thin films are routinely carried out using EBSD and TEM. In situ-TEM is another key growing thread in our group to visualize growth and phase transition.

About Us

The research on nanotechnology is taking a rapid path towards nanomanufacturing to materialize breakthroughs of nanoscience and nanotechnology in to practical reality. The main objective of the nanoscale materials and devices laboratory at IIT Mandi is to achieve controlled growth of various 1D, 2D materials and thin films to overcome the fundamental challenges in nanomanufacturing and to develop devices. Our group is focused towards industrial needs in the areas of nanoelectronics, nanomechanics, energy, smart materials and sensors. Understanding the microstructure and organization of nanostructures are critical for controlling their electrical, optical, mechanical and catalytic properties. Such understanding will provide the ability to control the growth and design of nanostructures and can serve as roadmap in manufacturing nanoscale devices. Manufacturing at nanoscale involves large scale, reliable, economic and controlled production of nanoscale materials, structures, devices and requires interdisciplinary research approach. We use this interdisiplinary materials engineering approach with our expertise on vapor phase growth, electron microscopy, nanomechanics and several in-situ characterization methods to solve problems related to nanoscale materials and devices for various applications. Our group’s current materials of interests are aligned CNTs, CVD graphene, MoS2 and smart materials such as VO2 that shows abrupt property change across the phase transition. Being a materials group, we are always interested to discuss and collaborate with motivated researchers from applied physics, materials chemistry, electrical and mechanical engineering and across other disciplines.
