The current is computed for both n- and p-type BP, and the difference thereof is attributed to the particle-hole asymmetry. The four laws of black hole mechanics are physical properties that black holes are believed to satisfy. The laws, analogous to the laws of thermodynamics, were discovered by Jacob Bekenstein, Brandon Carter, and James Bardeen. Further considerations were made by Stephen Hawking.
