Versatile Large-Area Custom-Feature van der Waals Epitaxy of Topological Insulators
Tanuj Trivedi, Anupam Roy, Hema C. P. Movva +4
As the focus of applied research in topological insulators (TI) evolves, the need to synthesize large-area TI films for practical device applications takes center stage. However, c…
Angular dependence of magnetization reversal in epitaxial chromium telluride thin films with perpendicular magnetic anisotropy
Tanmoy Pramanik, Anupam Roy, Rik Dey +5
We investigate magnetic anisotropy and magnetization reversal mechanism in chromium telluride thin films grown by molecular beam epitaxy. We report existence of strong perpendicula…
Detection of current induced spin polarization in epitaxial BiTe thin film
Rik Dey, Anupam Roy, Tanmoy Pramanik +5
We electrically detect charge current induced spin polarization on the surface of molecular beam epitaxy grown BiTe thin film in a two-terminal device with a ferromagnetic…
Air Stable Doping and Intrinsic Mobility Enhancement in Monolayer by Amorphous Encapsulation
Amritesh Rai, Amithraj Valsaraj, Hema C. P. Movva +12
To reduce Schottky-barrier-induced contact and access resistance, and the impact of charged impurity and phonon scattering on mobility in devices based on 2D transition metal dicha…
A sub-1-volt analog metal oxide memristive-based synaptic device for energy-efficient spike-based computing systems
Cheng-Chih Hsieh, Anupam Roy, Yao-Feng Chang +2
Nanoscale metal oxide memristors have potential in the development of brain-inspired computing systems that are scalable and efficient1-3. In such systems, memristors represent the…
Nanodot to Nanowire: A strain-driven shape transition in self-organized endotaxial CoSi2 on Si (100)
J. C. Mahato, Debolina Das, R. R. Juluri +4
We report a phenomenon of strain-driven shape transition in the growth of nanoscale self-organized endotaxial CoSi2 islands on Si (100) substrates. Small square shaped islands as s…
