Novel attributes of steep-slope staggered type heterojunction p-channel electron-hole bilayer tunnel field effect transistor

In this paper, the electrical characteristics and sensitivity analysis of staggered type p-channel heterojunction electron-hole bilayer tunnel field effect transistor (HJ-EHBTFET) are thoroughly investigated via simulation study. The minimum lattice mismatch between InAs/GaAs0.1Sb0.9 layers besides low carrier effective mass of materials provides high probability ...

Engineering the Electron-Hole Bilayer Tunneling Field- Effect Transistor

The electron-hole (EH) Bilayer Tunneling FieldEffect Transistor promises to eliminate heavy-doping band-tails enabling a smaller subthreshold swing voltage. Nevertheless, the electrostatics of a thin structure must be optimized for gate efficiency. We analyze the tradeoff between gate efficiency versus on-state conductance to find the optimal device design. Once the EH Bilayer is optimized for ...

Comment on ‘Germanium electron–hole bilayer tunnel field-effect transistors with a symmetrically arranged double gate’

In this comment we demonstrate that the inclusion of field-induced quantum confinement effects through appropriate discretization of conduction and valence bands refutes the suitability of a germanium electron–hole bilayer tunnel field-effect transistor with symmetrically arranged gates (Jeong et al 2015 Semicond. Sci. Technol. 30 035021). Delayed alignment of the first electron and hole energy...

Bilayer graphene. Electron-hole asymmetric integer and fractional quantum Hall effect in bilayer graphene.

The nature of fractional quantum Hall (FQH) states is determined by the interplay between the Coulomb interaction and the symmetries of the system. The distinct combination of spin, valley, and orbital degeneracies in bilayer graphene is predicted to produce an unusual and tunable sequence of FQH states. Here, we present local electronic compressibility measurements of the FQH effect in the low...
