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…
Intra-Domain Periodic Defects in Monolayer MoS
Anupam Roy, Rudresh Ghosh, Amritesh Rai +8
We present an ultra-high vacuum scanning tunneling microscopy (STM) study of structural defects in molybdenum disulfide thin films grown on silicon substrates by chemical vapor dep…
High density nonmagnetic cobalt in thin films
Nasrin Banu, Surendra Singh, Saibal Basu +3
Recently high density (HD) nonmagnetic (NM) cobalt has been discovered in a cobalt thin film, grown on Si(111). This cobalt film had a natural cobalt oxide at the top. The oxide la…
Density-Dependent Quantum Hall States and Zeeman Splitting in Monolayer and Bilayer WSe
Hema C. P. Movva, Babak Fallahazad, Kyounghwan Kim +5
We report a study of the quantum Hall states (QHSs) sequence of holes in mono- and bilayer WSe. The QHSs sequence transitions between predominantly even and predominantly odd f…
