Atikur Rahman obtained his PhD in Electronic Transport Properties of Nanowires in 2009 from Saha Institute of Nuclear Physics, Kolkata (degree awarded by Calcutta University). He was a postdoctoral fellow at Johns Hopkins University from 2009 to 2012 and research associate (2012-2016) at Center for Functional Nanomaterials, Brookhaven National Lab before joining IISER Pune in 2016.
The Nano Energy & Quantum Transport Lab led by Dr. Atikur Rahman at IISER Pune is mainly interested in understanding fundamental charge transport properties and applications of quasi-1D (nanowires and nanotubes), 2D materials and mixed-dimensional van der Waals heterostructures. The group studies electronic transport properties under varying temperature, magnetic field and light conditions to understand the effects of interactions and disorders on the charge transport properties of quantum confined systems. The knowledge of various scattering mechanisms and interactions among the charge carriers is important not only from the fundamental point of view but also necessary for making efficient energy harvesting devices and ultra-sensitive sensors. For fabricating nanodevices, apart from using conventional lithography techniques such as e-beam and optical lithography the group also uses self-assembly based nanopatterning. These nanodevices then characterized using various electrical (current-voltage, resistivity, dielectric, differential conductance, deep level transient spectroscopy, low frequency noise etc.), optical (Raman, PL, UV-VIS) and optoelectrical (photo-current, transient photo-voltage) techniques. The group has exhaustive experience in (i) synthesis of 2D and 1D materials, (ii)nanodevice fabrication, (iii)various electronic and opto-electronic measurements, (iv)nanostructure based solar energy harvesting, (v) tuning materials properties through nanotexturing. The group is also involved in building new experimental setup and encourages students in setting up new measurement capabilities.
