Ohmic contacts to n-GaN The valence bond of GaN shows obvious ionicity, and there is no high surface density of states at the interface between metal and GaN, so the height of contact barrier mainly depends on the work function of the metal. For n-GaN ohmic contact, as discussed in the last section, the preferred method is to select

Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = RΔV. Where I I is current, \Delta V ΔV is electric potential difference, and R R is resistance.
