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…
AC Measurement of the Nernst effect of thin films at low temperatures
Yuxiao Wu, Aviad Frydman, Arnab Roy
We describe an alternating current method to measure the Nernst effect in superconducting thin films at low temperatures. The Nernst effect is an important tool in the understandin…
Stacking Order Driven Optical Properties and Carrier Dynamics in ReS2
Yongjian Zhou, Nikhilesh Maity, Amritesh Rai +8
Two distinct stacking orders in ReS2 are identified without ambiguity and their influence on vibrational, optical properties and carrier dynamics are investigated. With atomic reso…
Accelerated Carrier Recombination by Grain Boundary/Edge Defects in MBE Grown Transition Metal Dichalcogenides
Ke Chen, Anupam Roy, Amritesh Rai +5
Defect-carrier interaction in transition metal dichalcogenides (TMDs) play important roles in carrier relaxation dynamics and carrier transport, which determines the performance of…
Superconductivity of Cobalt in Thin Films
Nasrin Banu, M. Aslam, Arpita Paul +8
Due to competing long range ferromagnetic order, the transition metals Fe, Co and Ni are not superconductors at ambient pressure. While superconductivity was observed in a non-magn…
Carrier Trapping by Oxygen Impurities in Molybdenum Diselenide
Ke Chen, Anupam Roy, Amritesh Rai +7
Understanding defect effect on carrier dynamics is essential for both fundamental physics and potential applications of transition metal dichalcogenides. Here, the phenomenon of ox…
