Abstract:
A scalable approach for the synthesis of black phosphorus (BP) material thin films over large areas is described. A red phosphorus (RP) material thin film may be deposited on a substrate followed by conversion to a BP material thin film using high-pressure alone or high pressure and high temperature. A thin-film of dielectric material such as hexagonal boron nitride (hBN) can be formed on a RP material film before the conversion is performed to improve the crystalline quality and stability of the converted BP material. Surprisingly, an atomically sharp and defect-free interface can be formed between the converted BP material and hBN. The BP material has high crystalline uniformity and can be used to fabricate thin-film transistors and optoelectronic devices such as infrared photodetectors.

Claim (Index 25):
The method of  claim 18 , further comprising depositing a first layer of dielectric material on the substrate prior to depositing the layer of red phosphorus material, so that the layer of red phosphorus material is encapsulated by dielectric material.
