Signature of spin-resolved quantum point contact in p-type trilayer WSe van der Waals heterostructure
K. Sakanashi, P. Krüger, K. Watanabe +5
In this study, the electrostatically induced quantum confinement structure, quantum point contact, has been realized in p-type trilayer tungsten diselenide-based van der Waals hete…
Quantized exciton-exciton annihilation in monolayer WS2 on SrTiO3 substrates with atomically flat terraces
Yuto Kajino, Kohei Sakanashi, Nobuyuki Aoki +4
Monolayer materials are strongly affected by their potential fluctuations, which are induced by an intrinsic corrugation or the surface roughness of the substrate. We compare the e…
Investigation of laser-induced-metal phase of and its contact property via scanning gate microscopy
Kohei Sakanashi, Hidemitsu Ouchi, Kota Kamiya +8
Although semiconductor to metal phase transformation of MoTe by high-density laser irradiation of more than 0.3 MW/cm has been reported, we reveal that the laser-induce…
Detecting weak coupling in mesoscopic systems with a nonequilibrium Fano resonance
S. Xiao, Y. Yoon, Y. -H. Lee +5
A critical aspect of quantum mechanics is the nonlocal nature of the wavefunction, a characteristic that may yield unexpected coupling of nominally-isolated systems. The capacity t…
Tuning the Fano Resonance with an Intruder Continuum
J. Fransson, M. -G. Kang, Y. Yoon +5
Through a combination of experiment and theory we establish the possibility of achieving strong tuning of Fano resonances (FRs), by allowing their usual two-path geometry to interf…
Experimental evidence for direct insulator-quantum Hall transition in multi-layer graphene
Chiashain Chuang, Li-Hung Lin, Nobuyuki Aoki +7
We have performed magnetotransport measurements on a multi-layer graphene flake. At the crossing magnetic field Bc, an approximately temperature-independent point in the measured l…
