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…
