Ehsanur Rahman, Abir Shadman, Sudipta Romen Biswas +2
In this work, we investigate the transport phenomena in compound semiconductor material based buried channel Quantum Well MOSFET with a view to developing a simple and effective mo…
Interplay Between Near-Field Radiative Coupling and Space Charge Effects in a Micro gap Thermionic Energy Converter under Fixed Heat Input
Ehsanur Rahman, Alireza Nojeh
We investigate the performance of a micro gap vacuum thermionic energy converter considering the loss mechanisms due to the space charge effect and interelectrode radiative heat tr…
Adsorbate-enhanced field-emission from single-walled carbon nanotubes: a comparative first-principles study
Ehsanur Rahman, Alireza Nojeh
We report a comparative ab-initio study of different types of adsorbates and their adsorption mechanism on the field-emission performance of single-walled carbon nanotubes by analy…
