Abstract

Using high-spatial resolution scanning magneto-photoluminescence (PL) of InP/GaInP2 quantum dots (QDs) we revealed a formation of fractionally charged magneto-electron (em) – a localized particle, consisting of a few magnetic flux quanta self-generated by a single electron. It can be considered as a single particle version of composite fermions involved in fractional quantum Hall effect (FQHE) and used for realization of topological quantum computing schemes. Using six electron QD we demonstrate optically induced pairing (fusion) and interchange (braiding) of ems, which are the necessary steps in the operation of the topological quantum gate.

Abstract

We report non-contact local doping of a monolayer WSe2 transferred onto a piezoelectric substrate having surface potential wells (SPWs) induced by structural inhomogeneities. We used epitaxial GaN and InP/GaInP2 structures, in which there are SPWs ∼0.2 V deep and 0.1–2 μm in size. Using surface topography and potential scanning probe microscopy, as well as optical reflectance, photoluminescence, and Raman spectroscopy measurements, we observed strong enhancement of charged exciton emission and Raman intensity in the SPW regions of the monolayer WSe2, which indicate on piezoelectric doping at a level n ≥ 1012 cm−2 on a length scale ∼0.2–1 μm. Our results can be used to create electron/hole quantum puddles with anyon states in transition metal dichalcogenides, promising for the development of room temperature and magnetic-field-free fault-tolerant topological quantum computing.
