Abstract

We demonstrate that the energy bandgap of layered, high-dielectric α-MoO₃ can be reduced to values viable for the fabrication of 2D electronic devices. This is achieved through embedding Coulomb charges within the high dielectric media, advantageously limiting charge scattering. As a result, devices with α-MoO₃ of ∼11 nm thickness and carrier mobilities larger than 1100 cm² V^-1 s^-1 are obtained.
