The effects of electric field on electronic and thermal properties of bilayer boron phosphide: Beyond nearest neighbor approximation

摘要: Abstract The behaviors electronic structure and density of states (DOS) biased AB bilayer boron phosphide (BP) with two configuration types (B P B B) investigated by the fifth nearest neighbor tight binding model. bias voltage temperature dependence contribution heat capacity, electrical thermal conductivity, paramagnetic susceptibility Lorenz number have been using linear response theory. increases energy band gap in while configuration, decreases to zero at critical then again as beyond voltage. For type, properties is larger for stronger U ≤ 1.0 eV further increasing range > eV. linearly unlike which applying leads decreasing its properties. type showed more sensitivity than their differences up 1000 K.
