Publikováno v: Carbon. 167(No. 15):785-791

Hexagonal boron nitride (h-BN) is a layered material that is generating interest in various fields owing to its fascinating properties. We present a multi-stranded analysis of carbon defects in h-BN using intentionally carbon (C)-doped h-BN crystals.

Electronic states and modulation doping of hexagonal boron nitride trilayers

Autor: Taishi Haga, Yoshitaka Fujimoto, Susumu Saito, Yuuto Matsuura

Publikováno v: Physical Review Materials. 5:094003

We study the stabilities and geometric and electronic properties of hexagonal boron nitride $(h\text{\ensuremath{-}}\mathrm{BN})$ trilayers by using first-principles electronic-structure calculations within the framework of the density functional the

STM visualization of carbon impurities in sandwich structures consisting of hexagonal boron nitride and graphene

Autor: Taishi Haga, Susumu Saito, Yoshitaka Fujimoto

Publikováno v: Japanese Journal of Applied Physics. 58:SIIB03

We study the electronic structures and scanning tunneling microscopy (STM) images of heterostructures consisting of pristine h-BN, graphene, and C-doped h-BN layers using first-principles total-energy calculations within the framework of the density
