Channel length dependence of the formation of quantum dots in GaN/AlGaN FETs
Kazuma Matsumura, Takaya Abe, Takahito Kitada +5
Quantum dots can be formed in simple GaN/AlGaN field-effect-transistors (FETs) by disordered potential induced by impurities and defects. Here, we investigate the channel length de…
Formation of quantum dots in MoS2 with cryogenic Bi contacts and intrinsic Schottky barriers
Riku Tataka, Alka Sharma, Tomoya Johmen +4
The recent advancement in two-dimensional (2D) materials-based quantum confinement has provided an opportunity to investigate and manipulate electron transport for quantum applicat…
Complete set of bound negative-parity states in the neutron-rich 18N nucleus
S. Ziliani, M. Ciemała, F. C. L. Crespi +54
High-resolution gamma-ray spectroscopy of 18N is performed with the Advanced GAmma Tracking Array AGATA, following deep-inelastic processes induced by an 18O beam on a 181Ta target…
Gate voltage dependence of noise distribution in radio-frequency reflectometry in gallium arsenide quantum dots
Motoya Shinozaki, Yui Muto, Takahito Kitada +10
We investigate gate voltage dependence of electrical readout noise in high-speed rf reflectometry using gallium arsenide quantum dots. The fast Fourier transform spectrum from the…
Spin orbit field in a physically defined p type MOS silicon double quantum dot
Marian Marx, Jun Yoneda, Ángel Gutiérrez Rubio +10
We experimentally and theoretically investigate the spin orbit (SO) field in a physically defined, p type metal oxide semiconductor double quantum dot in silicon. We measure the ma…
Coherence of a driven electron spin qubit actively decoupled from quasi-static noise
Takashi Nakajima, Akito Noiri, Kento Kawasaki +11
The coherence of electron spin qubits in semiconductor quantum dots suffers mostly from low-frequency noise. During the last decade, efforts have been devoted to mitigate such nois…
