Observation of Electronic Modes in Open Cavity Resonator
Hwanchul Jung, Dongsung T. Park, Seokyeong Lee +9
The resemblance between electrons and optical waves has strongly driven the advancement of mesoscopic physics. However, electron waves have yet to be understood in open cavity stru…
Numerical Reconstruction of 2D Magnetic Focusing Experiments
Dongsung T. Park, Seokyeong Lee, Uhjin Kim +3
Spatial aspects in quantum mechanics are often difficult to model in geometrically intricate settings that are typical of mesoscopic physics. In such cases, predicting the device b…
Ultrafast energy relaxation of quantum dot-generated 2D hot electrons
Dongsung T. Park, Dongkun Kim, Uhjin Kim +8
Through a series of transverse magnetic focusing experiments, we show that hot electrons in a two-dimensional electron gas system undergo an ultrafast relaxation when generated by…
Fast raster scan multiplexed charge stability measurements toward high-throughput quantum dot array calibration
Wonjin Jang, Min-Kyun Cho, Myungwon Lee +6
We report raster scan multiplexed charge-stability diagram measurements for tuning multiple gate-defined quantum dots in GaAs/AlGaAs heterostructures. We evaluate the charge sensit…
Attractive Coulomb interactions in a triple quantum dot
Changki Hong, Gwangsu Yoo, Jinhong Park +7
Electron pairing due to a repulsive Coulomb interaction in a triple quantum dot (TQD) is experimentally studied. It is found that electron pairing in two dots of a TQD is mediated…
Numerical Simulation of Quantized Current Generated by a Quantum Dot Pump
Ye-Hwan Ahn, Yunchul Chung
The quantized current generated by a quantum dot pump is calculated numerically. The numerical simulation is done by dividing the time varying potential into many static potentials…
