Award-winning publication: Space-Charge Limited Transport in Large-Area Monolayer Hexagonal Boron Nitride

Published in: Nano Letters, 2015, 15


Hexagonal boron nitride (hBN) is a material employed in nano electronic devices as a dielectric substrate. One of the more significant findings to emerge from this study is that charge carriers can be injected in monolayer hBN. The future development of hBN devices with a stable charge density compensated by impurity dopants or field effect will enable hBN to be applied to ultraviolet optoelectronic devices. This research could serve as a base for future studies concerning the integration of hBN in semiconductor heterostructures for the realization of high-efficiency deep ultraviolet optoelectronic devices. Fabrication of such devices will make a profound impact on the broad areas of society including household appliances and medical instruments.
