description: The subject of the graduate qualification work is transition metal dichalcogenides on piezoelectric substrates. The aim of the work is to detect local doping of twoâdimensional transition metal dichalcogenide WSe2 using surface potential wells of piezoelectric substrates. During the study, two-dimensional WSe2 flakes were applied by mechanical exfoliate to substrates with surface potential wells: GaN and InP/GaInP2, as well as to test substrates GaInP2 and SiO2/Si. Further, the obtained samples were studied by photoluminescence spectroscopy,Â  Raman scattering of light, as well as atomic and Kelvin force microscopy. The experimental results obtained were processed using applied software tools: Origin, Image Analysis, Gwyddion.Local doping was detected at the level of nâ10^12cm-2 and at a length scale of 0.2â1.5 microns at the locations of surface potential wells of the WSe2/GaN and WSe2/InP/GaInP2 structures.Â  The results obtained can be used to create Wigner localization states and stable quantum calculations at room temperatures.
