1. A method of forming a composite tip for a scanning tunneling microscope (“STM”), comprising:
using a nanomanipulator to select a single crystal wide-band-gap semiconductor from an array of formed single crystal wide-band-gap semiconductors epitaxially grown selectively on a crystalline substrate, wherein the single crystal wide-band-gap semiconductor comprises a group III-N nanowire;
preparing an electrically conductive wire to provide a substantially flat end surface that is substantially perpendicular to the wire length direction;
transferring the single crystal wide-band-gap semiconductor from the growth substrate to the substantially flat end surface of the electrically conductive wire; and
affixing the single crystal wide-band-gap semiconductor to the substantially flat end surface of the electrically conductive wire to form the composite tip.
