This data corresponds to the characterization of a transfer-free ultrathin heterostructure of a 2D semiconductor and high-k dielectric, and the resulting field-effect transistors. Monolayer MoS2 was grown directly via chemical vapor deposition on 20 nm of amorphous alumina deposited via atomic layer deposition on a silicon substrate. This method of integrating 2D MoS2 with a high-k dielectric results in superior performance in low-power electronics figures of merit. DOI:
