Simulation of temperature profile for the electron- and the lattice-systems in laterally structured layered conductors
Le Yang, Ruijie Qian, Zhenghua An +2
Electrons in operating microelectronic semiconductor devices are accelerated by locally varying strong electric field to acquire effective electron temperatures nonuniformly distri…
Revisiting the Dipole Model for a Thermal Infrared Near-Field Spectroscope
Florian Herz, Zhenghua An, Susumu Komiyama +1
We determine the scattered near-field and directly emitted power of a heated spherical nanoparticle above a sample within the framework of fluctuational electrodynamics using the d…
Gate-Control of Spin Precession in Quantum Hall Edge States
T. Nakajima, Kuan-Ting Lin, S. Komiyama
Electrical control and detection of spin precession are experimentally demonstrated by using spin-resolved edge states in the integer quantum Hall regime. Spin precession is trigge…
Mobility modulation effects in a double quantum well infrared photon-detector
Ting-Ting Kang, Susumu Komiyama, Takeji Ueda +2
An electrically isolated quantum well (QW) island can be positively charged by incoming infrared photon, because its electrons absorb photon energy via intersubband transition and…
