Reverse magnetic vortex curling direction of ferromagnetic nanodisk
Wen-Ming Ju, Mark Tuominen, Nihar Pradhan +2
We reverse the magnetic vortex curling direction of ferromagnetic nanodisk by applying a circular Oersted field. The nanodisk is fabricated without breaking its symmetry. The Oerst…
Pronounced photovoltaic response from multi-layered transition-metal dichalcogenides PN-junctions
Shahriar Memaran, Nihar R. Pradhan, Zhengguang Lu +7
Transition metal dichalcogenides (TMDs) are layered semiconductors with indirect band gaps comparable to Si. These compounds can be grown in large area, while their gap(s) can be t…
Field-Effect Transistors Based on Few-Layered alpha-MoTe_2
Nihar R. Pradhan, Daniel Rhodes, Simin Feng +6
Here we report the properties of field-effect transistors based on few layers of chemical vapor transport grown alpha- MoTe_2 crystals mechanically exfoliated onto SiO_2. We perfor…
