Optically initialized robust valley-polarized holes in monolayer WSe2
A robust valley polarization is a key prerequisite for exploiting valley pseudospin to carry information in next-generation electronics and optoelectronics. Although monolayer transition metal dichalcogenides with inherent spin-valley coupling offer a unique platform to develop such valleytronic devices, the anticipated long-lived valley pseudospin has not been observed yet. Here we demonstrate...

متن کاملSingle electron charging in optically active nanowire quantum dots.
We report optical experiments of a charge tunable, single nanowire quantum dot subject to an electric field tuned by two independent voltages. First, we control tunneling events through an applied electric field along the nanowire growth direction. Second, we modify the chemical potential in the nanowire with a back-gate. We combine these two field-effects to isolate a single electron and indep...
متن کاملNuclear Spin Phenomena in Optically Active Semiconductor Quantum Dots
The motivating background for this thesis lies in the recent development in the coherent optical control of electron spin states in semiconductor quantum dots. One possible and attractive application for these achievements is a physical implementation of a quantum computer based on spin qubits (quantum bit) in quantum dots. However, one of the obstacles in building such quantum computer is deco...
متن کاملValley depolarization in monolayer WSe2
We have systematically examined the circular polarization of monolayer WSe2 at different temperature, excitation energy and exciton density. The valley depolarization in WSe2 is experimentally confirmed to be governed by the intervalley electron-hole exchange interaction. More importantly, a non-monotonic dependence of valley circular polarization on the excitation power density has been observ...
