  • Method of making nanotube permeable base transistor
    Patent number: 6774052
    Abstract: A method of making a permeable base transistor (PBT) is disclosed. According to the method, a semiconductor substrate is provided, a base layer is provided on the substrate, and a semiconductor layer is grown over the base layer. The base layer includes metallic nanotubes, which may be grown or deposited on the semiconductor substrate. The nanotube base layer separates emitter and collector layers of semiconductor material.
    Type: Grant
