Prof. Abhishek Singh is involved in diverse fields including machine learning (ML), 2D materials, thermoelectrics, catalysis, optical properties, topological materials and defects using density functional based approaches. In field of machine learning, Prof. Singh’s group focuses on the development of advanced materials database and building ML based models for accurate prediction of specific properties. His group has established India’s first computational materials database aNANt (http://anant.mrc.iisc.ac.in/), which consists of electronic and structural properties of 25000 MXenes. This database is currently the world’s largest database on 2D materials. The machine learning based approaches accelerate the development of materials by reducing redundancies in experiments and promoting intelligent selection of materials.

His group also focuses on two dimensional materials such as graphene, metallic sheets, MXenes, heterostructures, metallic clusters and nanowires. Several phenomena such as semiconductor to metallic transition, charge transfer, optical and vibrational properties occurring due to application of pressure/strain on these 2D materials are studied. Currently, he is also involved in studying the effect of application of pressure on the electronic, optical and exciton properties of materials. In the field of thermoelectrics, Prof. Singh’s group is involved actively in discovering materials and mechanisms for enhancement of thermoelectric efficiency. The research work includes discovering mechanisms for increasing power factor of material by reducing thermal conductivity while simultaneously enhancing the Seebeck’s coefficient and electrical conductivity of a material. Moreover, the application of semiconducting material in efficient field effect transistor and optoelectronic devices depends on the ubiquitously present point defects in the host materials. His group extensively studies the defect physics of various class of low dimensional (2D and 1D) as well as bulk wide-band-gap semiconducting materials. The defect-thermodynamics of the host materials are investigated to predict their practical implication in the electrical and optical properties. His group also perform defect engineering by 2D/2D van der Waal heterostructuring and applying strain to tune the electrical conductivity, which enhance the performance of future nano-electronic devices.
