Transistors based on Novel 2-D Monolayer Semiconductors Bi2O2Se, InSe, and MoSi2N4 for Enhanced Logic Density Scaling
Keshari Nandan, Ateeb Naseer, Amit Agarwal +2
Making ultra-short gate-length transistors significantly contributes to scaling the contacted gate pitch. This, in turn, plays a vital role in achieving smaller standard logic cell…
Room Temperature Ferroelectricity, Ferromagnetism, and Anomalous Hall Effect in Half-metallic Monolayer CrTe
Imran Ahamed, Atasi Chakraborty, Pushpendra Yadav +4
Two-dimensional materials hosting ferroelectricity and ferromagnetism are crucial for low-power and high-speed information processing technologies. However, intrinsic 2D multiferro…
Designing power efficient transistors using narrow bandwidth materials from the MA2Z4 monolayer series
Keshari Nandan, Somnath Bhowmick, Yogesh S. Chauhan +1
The subthreshold leakage current in transistors has become a critical limiting factor for realizing ultra-low-power transistors. The leakage current is predominantly dictated by th…
Two-dimensional MoSi2N4: An Excellent 2D Semiconductor for Transistors
Keshari Nandan, Barun Ghosh, Amit Agarwal +2
We report the performance of field-effect transistors (FETs), comprised of mono-layer of recently synthesized layered two-dimensional MoSi2N_4 as channel material, using the first…
PdSe2 based field-effect transistors
Keshari Nandan, Amit Agarwal, Somnath Bhowmick +1
Pentagonal PdSe2 is a promising candidate for layered electronic devices, owing to its high air-stability and anisotropic transport properties. Here, we investigate the performance…
Anisotropic plasmons, excitons and electron energy loss spectroscopy of phosphorene
Barun Ghosh, Piyush Kumar, Anmol Thakur +3
In this article, we explore the anisotropic electron energy loss spectrum (EELS) in monolayer phosphorene based on ab-initio time dependent density functional theory calculations.…
Thickness and electric field dependent polarizability and dielectric constant in phosphorene
Piyush Kumar, B. S. Bhadoria, Sanjay Kumar +3
Based on extensive first principle calculations, we explore the thickness dependent effective di- electric constant and slab polarizability of few layer black phosphorene. We find…
Effective Doping of Monolayer Phosphorene by Surface Adsorption of Atoms for Electronic and Spintronic Applications
Priyank Rastogi, Sanjay Kumar, Somnath Bhowmick +2
We study the effect of surface adsorption of 27 different adatoms on the electronic and magnetic properties of monolayer black phosphorus using density functional theory. Choosing…
