Effect of Image Potential on Spin Polarized Transport through Magnetic Tunnel Junctions
Tehseen Zahra Raza, Hassan Raza
We study the effect of image potential on spin polarized transport through Fe/MgO/Fe magnetic tunnel junctions in the presence of symmetry filtering. The image potential is include…
A hands-on laboratory and computational experience for nanoscale materials, devices and systems education for electronics, spintronics and optoelectronics
Hassan Raza, Tehseen Z. Raza
To enhance the undergraduate and graduate engineering education for nanoscale materials, devices and systems, we report a multi-disciplinary course based on the integration of theo…
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…
