Structural and Magnetic Properties of Molecular Beam Epitaxy Grown Chromium Selenide Thin Films
Anupam Roy, Rik Dey, Tanmoy Pramanik +5
Chromium selenide thin films were grown epitaxially on AlO(0001) and Si(111)-(77) substrates using molecular beam epitaxy (MBE). Sharp streaks in reflection h…
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…
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…
Write error rate of spin-transfer-torque random access memory including micromagnetic effects using rare event enhancement
Urmimala Roy, Tanmoy Pramanik, Leonard F. Register +1
Spin-transfer-torque random access memory (STT-RAM) is a promising candidate for the next-generation of random-access-memory due to improved scalability, read-write speeds and endu…
Structural and Electrical Properties of MoTe and MoSe Grown by Molecular Beam Epitaxy
Anupam Roy, Hema C. P. Movva, Biswarup Satpati +7
We demonstrate the growth of thin films of molybdenum ditelluride and molybdenum diselenide on sapphire substrates by molecular beam epitaxy. In-situ structural and chemical analys…
Perpendicular magnetic anisotropy and spin glass-like behavior in molecular beam epitaxy grown chromium telluride thin films
Anupam Roy, Samaresh Guchhait, Rik Dey +4
Reflection high energy electron diffraction (RHEED), scanning tunneling microscopy (STM), vibrating sample magnetometry and other physical property measurements are used to investi…
Voltage Induced Switching of Nanomagnets in Topological Insulator Magnetoelectric Devices through Ruderman-Kittel-Kasuya-Yosida Interactions
Bahniman Ghosh, Urmimala Roy, Rik Dey +3
In this letter, we demonstrate switching of nanomagnets through RKKY interactions in topological insulator-based magnetoelectric devices. The switching speed is dependent on the si…
