Abstract:Diamond is a material with promising electronics applications but with challenges in effective doping. Cubic boron nitride (cBN), due to its similar lattice structure, is ideal for forming heterostructures with diamond, to modify electronic properties and especially shift the band positions. Here it is demonstrated how integrating cBN layers of finite thickness in diamond can induce an electronic band offset near the polarized diamond-cBN interface. Beyond the direct density functional theory computations, an … Show more
