Nanoscale mapping of stacking-dependent work function and local photoresponse in CVD-grown MoS2 bilayers by KPFM
Anagha Gopinath, Faiha Mujeeb, Subhabrata Dhar +1
Stacking order in bilayers of transition metal dichalcogenides (TMDs) controls structural symmetry and layer-to-layer interactions, offering a direct route to tune their electronic…
Si-Ga2O3/p-GaN epitaxial heterostructure based self-powered and visible-blind UV photodetectors with fast and electrically tuneable response time
Ajoy Biswas, Amandeep Kaur, Bhabani Prasad Sahu +5
n-Ga2O3/p-GaN heterojunction based photodetector devices are fabricated on Si-doped (-201) β-Ga2O3 epitaxial layers grown by pulsed laser deposition (PLD) technique on p-type c-Ga…
CVD grown bilayer MoS2 based artificial optoelectronic synapses for arithmetic computing and image recognition applications
Umakanta Patra, Subhrajit Sikdar, Roshan Padhan +3
Demand for lower computing power has rapidly increased. In this context, brain-inspired neuromorphic computing, which integrate data storage and processing, has attracted significa…
Spontaneous growth of perfectly circular domains of MoS2 monolayers using chemical vapour deposition technique
Umakanta Patra, Subhabrata Dhar
Very large-scale integration of devices in a circular pattern has several advantages over the commonly used rectangular grid layout. For the development of such integrated circuits…
High-energy electron-beam induced defect engineering of monolayer MoS2 for tunable optical properties
Anagha Gopinath, Faiha Mujeeb, Subhabrata Dhar +1
Structural defects in 2D-transition metal dichalcogenides are critical in modulating their optical and electrical behavior. Nevertheless, precise defect control within the monolaye…
Experimental demonstration of two distinct pathways of trion generation in monolayer MoS2
Faiha Mujeeb, Arkaprava Chowdhury, Anindya Datta +1
Excitation power and energy dependent photoluminescence (PL) and transient absorption spectroscopy (TAS) studies are carried out on chemical vapour deposition (CVD) grown 1L-MoS2 f…
