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…
Armchair graphene nanoribbons: Electronic structure and electric field modulation
Hassan Raza, Edwin C. Kan
We report electronic structure and electric field modulation calculations in the width direction for armchair graphene nanoribbons (acGNRs) using a semi-empirical extended Huckel t…
An atomistic quantum transport solver with dephasing for field-effect transistors
Hassan Raza, Edwin C. Kan
Extended Huckel theory (EHT) along with NEGF (Non-equilibrium Green's function formalism) has been used for modeling coherent transport through molecules. Incorporating dephasing h…
An Extended Huckel Theory based Atomistic Model for Graphene Nanoelectronics
Hassan Raza, Edwin C. Kan
An atomistic model based on the spin-restricted extended Huckel theory (EHT) is presented for simulating electronic structure and I-V characteristics of graphene devices. The model…
A theoretical model for single molecule incoherent scanning tunneling spectroscopy
Hassan Raza
Single molecule scanning tunneling spectroscopy (STS), with dephasing due to elastic and inelastic scattering, is of some current interest. Motivated by this, we report an extended…
