Our group works on the design and development of semiconductor nanoelectronic devices for beyond-CMOS applications and for green hydrogen generation. We are currently focusing on memristors for artificial synapses, ReRAMs for brain-inspired neuromorphic computing and data storage, high efficiency tandem solar cells with low EPBT and GHG emissions, and energy-efficient light emitting devices. 

We use low-cost processes and interface-engineering to fabricate flexible devices using emerging 3D, quasi-2D, and layered 2D semiconductors such as hybrid perovskites. The physical processes affecting the operation of these multi-layer devices, including generation and recombination mechanisms, and conventional and ionic charge transport mechanisms, are analyzed using techniques such as nano-scale imaging, deep level transient spectroscopy, impedance spectroscopy, low-temperature I-V and C-V measurements etc. The device structures are also simulated using 3D Silvaco and Synopsys TCAD tools to back our experimental work and to develop new analytical and semi-empirical models.
