Diamond Micro-Chip for Quantum Microscopy
Shahidul Asif, Hang Chen, Johannes Cremer +11
The nitrogen vacancy (NV) center in diamond is an increasingly popular quantum sensor for microscopy of electrical current, magnetization, and spins. However, efficient NV-sample i…
Above-room-temperature ferromagnetism in ultrathin van der Waals magnet
Hang Chen, Shahidul Asif, Kapildeb Dolui +16
Two-dimensional (2D) magnetic van der Waals materials provide a powerful platform for studying fundamental physics of low-dimensional magnetism, engineering novel magnetic phases,…
Revealing room temperature ferromagnetism in exfoliated FeGeTe flakes with quantum magnetic imaging
Hang Chen, Shahidul Asif, Matthew Whalen +11
Van der Waals material FeGeTe, with its long-range ferromagnetic ordering near room temperature, has significant potential to become an enabling platform for implementing n…
High-Performance HZO/InAlN/GaN MIS-HEMT with fT/fmax of 155/250 GHz
Peng Cui, Hang Chen, John Q. Xiao +1
Scaling of GaN high-electron-mobility transistors (HEMTs) usually increases gate leakage current and deteriorates breakdown characteristic, limiting the maximum drain current and o…
Investigation of spin orbit torque driven dynamics in ferromagnetic heterostructures
Xinran Zhou, Hang Chen, Yu-Sheng Ou +5
We use time-resolved (TR) measurements based on the polar magneto-optical Kerr effect (MOKE) to study the magnetization dynamics excited by spin orbit torques in Py (Permalloy)/Pt…
