Spin Arrays Confined by a Periodic Electrostatic Potential
Abstract
The second quantum evolution evolves around new capabilities to confine and control individual quantum systems. Here, we explore a new method of confining an array of individual electrons or holes by placing a semiconductor monolayer (e.g. MoSe2 or WSe2) on a twisted hBN substrate. A periodic electrostatic potential is formed on the top surface of the hBN substrate due to the polarization field from charge redistribution at the twisted interface. The generation of the moiré potential and the functional layer (i.e. doped semiconductors) are separated, thus offering flexibility in engineering the moiré potential and the choice of the functional layer. We hypothesize that this potential confines individual electrons and holes within the moiré supercell, consequently, modifying the spin dynamics and coupling between the spins. The successful completion of the proposed projects will make broad impacts in quantum simulation and electric field tunable magnetism.
