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…
Imaging non-local electron transport via local excess noise
Qianchun Weng, Susumu Komiyama, Zhenghua An +5
Noise is usually a hindrance to signal detection. As stressed by Landauer, however, noise can be an invaluable signal that reveals kinetics of charge particles. Understanding local…
Near-field Nanoscopy of Thermal Evanescent Waves on Metals
S. Komiyama, Y. Kajihara, K. Kosaka +2
Intense electromagnetic evanescent fields are thermally excited in near fields on material surfaces (at distances smaller than the wavelength of peak thermal radiation). The proper…
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…
Circuit QED using a semiconductor double quantum dot
H. Toida, T. Nakajima, S. Komiyama
Vacuum Rabi splitting is observed in a coupled qubit-resonator system consisting of a GaAs double quantum dot and a coplanar waveguide resonator. Derived values of the qubit-resona…
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…
Double quantum dots as a high sensitive submillimeter-wave detector
O. Astafiev, S. Komiyama, T. Kutsuwa
A single electron transistor (SET) consisting of parallel double quantum dots fabricated in a GaAs/AlGaAs heterostructure crystal is demonstrated to serve as an extre…
