Multiscale model for phonon-assisted band-to-band tunneling in semiconductors
Arvind Ajoy, S. E. Laux, Kota V. R. M. Murali +1
We present a TCAD compatible multiscale model of phonon-assisted band-to-band tunneling (BTBT) in semiconductors, that incorporates the non-parabolic nature of complex bands within…
Brillouin zone unfolding of Complex Bands in a nearest neighbour Tight Binding scheme
Arvind Ajoy, Kota V R M Murali, Shreepad Karmalkar
Complex bands in a semiconductor crystal, along a general direction , can be computed by casting Schrödinger's equation as a generalized polynomial ei…
High On-Off Ratio Bilayer Graphene Complementary Field Effect Transistors
Kausik Majumdar, Kota V. R. M. Murali, Navakanta Bhat +2
In this paper, we propose a novel S/D engineering for dual-gated Bilayer Graphene (BLG) Field Effect Transistor (FET) using doped semiconductors (with a bandgap) as source and drai…
External Bias Dependent Direct To Indirect Bandgap Transition in Graphene Nanoribbon
Kausik Majumdar, Kota V. R. M. Murali, Navakanta Bhat +1
In this work, using self-consistent tight-binding calculations, for the first time, we show that a direct to indirect bandgap transition is possible in an armchair graphene nanorib…
Intrinsic Limits of Subthreshold Slope in Biased Bilayer Graphene Transistor
Kausik Majumdar, Kota V. R. M. Murali, Navakanta Bhat +1
In this work, we investigate the intrinsic limits of subthreshold slope in a dual gated bilayer graphene transistor using a coupled self-consistent Poisson-bandstructure solver. We…
Electromagnetically induced transparency in superconducting quantum circuits : Effects of decoherence, tunneling and multi-level cross-talk
Zachary Dutton, K. V. R. M. Murali, William D. Oliver +1
We explore theoretically electromagnetically-induced transparency (EIT) in a superconducting quantum circuit (SQC). The system is a persistent-current flux qubit biased in a co…
