On the Possibility of an Electronic-structure Modulation Transistor
Hassan Raza, Tehseen Z. Raza, Tuo-Hung Hou +1
We present a novel electronic-structure modulation transistor (EMT), which can possibly be used for post-CMOS logic applications. The device principle is based on the bandwidth mod…
Strain and field modulation in bilayer graphene band structure
Hassan Raza, Edwin C. Kan
Using an external electric field, one can modulate the bandgap of Bernal stacked bilayer graphene by breaking A-~B symmetry. We analyze strain effects on the bilayer graphene using…
Non-equilibrium Green's function based single-band tight-binding model for Fe-MgO-Fe magnetic tunnel junction devices
Tehseen Raza, Hassan Raza
Motivated by observation of very high tunnel magnetoresistance (TMR) in Fe-MgO-Fe magnetic tunnel junction devices, we propose a theoretical model for these devices based on a sing…
Single-band tight-binding parameters for Fe-MgO-Fe magnetic heterostructures
Tehseen Z. Raza, Hassan Raza
We present a computationally efficient transferable single-band tight-binding model (SBTB) for spin polarized transport in heterostructures with an effort to capture the band struc…
Nonvolatile memory with molecule-engineered tunneling barriers
Tuo-Hung Hou, Hassan Raza, Kamran Afshari +2
We report a novel field-sensitive tunneling barrier by embedding C60 in SiO2 for nonvolatile memory applications. C60 is a better choice than ultra-small nanocrystals due to its mo…
Electrical transport in two dimensional electron and hole gas on Si(001)-(2x1) surface
Hassan Raza, Tehseen Z. Raza, Edwin C. Kan
Si(001)-(21) surface is one of the many two-dimensional systems of scientific and applied interest. It has two surface state bands (1) anti-bonding pi* band, which has acce…
