title: Isoelectronic Tungsten Doping in Monolayer MoSe2for Carrier Type Modulation.
abstract: Carrier-type modulation is demonstrated in 2D transition metal dichalcogenides as n-type monolayer MoSe2is converted to nondegenerate p-type monolayer Mo1-xWxSe2through isoelectronic doping. Although the alloys are mesoscopically uniform, the p-type conduction in monolayer Mo1-xWxSe2appears to originate from the upshift of the valenceband maximum toward the Fermi level at highly localized "W-rich" regions in the lattice.
