Conductance fluctuations in high mobility monolayer graphene : nonergodicity, lack of determinism and chaotic behavior
Cunha, Carlo Requiao da; Mineharu, Masaaki; Matsunaga, Masahiro; Matsumoto, Naoki; Chuang, Chiashain; Ochiai, Yuichi; Kim, Gil-Ho; Watanabe, Kenji; Taniguchi, Takashi; Ferry, David K.; Aoki, Nobuyuki (2016) [Artigo de periódico]We have fabricated a high mobility device, composed of a monolayer graphene flake sandwiched between two sheets of hexagonal boron nitride. Conductance fluctuations as functions of a back gate voltage and magnetic field ... -
Ion irradiation-induced foams in antimonide binary alloys : a combination of small energy bandgap with giant surface-to-bulk ratio
Giulian, Raquel; Bolzan, Charles Airton; Salazar, Josiane Bueno; Cunha, Carlo Requiao da (2020) [Artigo de periódico]This is a short review about the ion irradiation-induced foams in antimonide films. III–V semiconductors like InSb and GaSb can be transformed into solid foams with nanometric dimensions upon irradiation with swift heavy ... -
A method for finding the background potential of quantum devices from scanning gate microscopy data using machine learning
Cunha, Carlo Requiao da; Aoki, Nobuyuki; Ferry, David K.; Lai, Ying-Cheng (2022) [Artigo de periódico]The inverse problem of estimating the background potential from measurements of the local density of states is a challenging issue in quantum mechanics. Even more difficult is to do this estimation using approximate methods ...
