Manufacturers encounter limitations in forming low resistance ohmic
electrical contact to semiconductor material P-type Gallium Nitride
(p-GaN), commonly used in photonic applications, such that the contact is
highly transparent to the light emission of the device. Carbon nanotubes
(CNTs) can address this problem due to their combined metallic and
semiconducting characteristics in conjunction with the fact that a fabric
of CNTs has high optical transparency. The physical structure of the
contact scheme is broken down into three components, a) the GaN, b) an
interface material and c) the metallic conductor. The role of the
interface material is to make suitable contact to both the GaN and the
metal so that the GaN, in turn, will make good electrical contact to the
metallic conductor that interfaces the device to external circuitry. A
method of fabricating contact to GaN using CNTs and metal while
maintaining protection of the GaN surface is provided.
