A method of forming lattice matched single crystal wide bandgap II-VI compound semiconductor films over a silicon substrate includes first cleaning ( ) the silicon substrate. A passivation layer is formed ( ), which may comprise arsenic, germanium, or CaF , among others. The lattice matched layer is then grown ( ) on the passivation layer.

An anode plate (10) for use in a field emission flat panel display device (8) includes a transparent substrate (26) having a plurality of spaced-apart, electrically conductive regions (28) are covered by a luminescent material (24) and from the anode electrode. A getter material (29) of porous silicon is deposited on the substrate (26) between the conductive regions (28) of the anode plate (10). The getter material (29) of porous silicon is preferably electrically nonconductive, opaque, and highly porous. Included are methods of fabricating the getter material (29) on the anode plate (10).

A gated resonant tunneling diode has a semiconductor mesa formed on a semiconductor substrate, a tunneling barrier layer between the mesa and the substrate, and a gate layered over the substrate about the mesa and aligned in close proximity to the tunneling barrier layer. A control voltage on the gate laterally constricts a potential well in the tunneling barrier to control the electrical size of a channel within which tunnelling occurs across the tunneling barrier layer. Preferably the gate and the tunneling layer are disposed at the base of the mesa, and the gate makes a rectifying Schottky junction in connection with the tunneling barrier layer. The device is constructed using an anisotropic etch to form the mesa with an undercut wall and a top portion overhanging the undercut wall, and a nonconformal deposition of gate material to align the gate with the top portion of the mesa.
