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…
Robust energy selective tunneling readout of singlet triplet qubits under large magnetic field gradient
Wonjin Jang, Jehyun Kim, Min-Kyun Cho +6
Fast and high-fidelity quantum state detection is essential for building robust spin-based quantum information processing platforms in semiconductors. The Pauli spin blockade (PSB)…
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…
