Current, photocurrent and thermocurrent of borophene-black phosphorus heterostructures
Abstract
In this paper, we calculated current–voltage characteristic curves (IV curves), Conductivity, real space charge distribution, transmission spectrum, photocurrent, and thermal current of the borophene-black phosphorus heterostructure. Our results show that the zigzag device has excellent photocurrent characteristics. The direction of photocurrent can be adjusted by changing the wavelength of incident light and adding gate voltage. The armchair device has excellent IV curve characteristics and good linear characteristics at low voltage. The armchair device also has good thermoelectric current properties. The position distribution of covalent bonds formed between atoms in this heterostructure is revealed by the real space charge distribution. Our results are significant for applying borophene-black phosphorus heterostructure in electric transport devices.
