摘要:
A method of generating a glow discharge plasma involves providing a pair of electrodes spaced apart by an electrode gap, and having a dielectric disposed in the electrode gap between the electrodes; placing the electrodes within an environment, wherein the electrode gap can be provided with a gas or gas mixture containing carbon at a specified pressure; and applying a rapid rise time voltage pulse across the electrodes to cause an extreme overvoltage condition, wherein the rapid rise time is less than a plasma generation time so that the extreme overvoltage condition occurs prior to current flow across the electrode gap. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要:
A dielectric barrier plasma discharge device consistent with certain embodiments of the present invention has a pair of electrodes spaced apart by an electrode gap. A dielectric is disposed between the electrodes. The electrode gap is provided with a gas at a specified pressure. A rapid rise time voltage pulse generator produces a voltage pulse across the electrodes to cause an extreme overvoltage condition, wherein the rapid rise time is less than a plasma generation time so that the extreme overvoltage condition occurs prior to current flow across the electrode gap. Due to the high voltages and high current densities, the product yields an extremely high instantaneous power density. This extreme overvoltage condition is also believed to lead to production of shock waves and runaway free electrons. The resulting plasma can be utilized to carry out many potential tasks including, but not limited to etching, deposition, and sterilization. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要:
A semiconductor structure consistent with certain implementations has a crystalline substrate oriented with a {111} plane surface that is within 10 degrees of surface normal. An epitaxially grown electrically insulating interlayer overlays the crystalline substrate and establishes a coincident lattice that mates with the surface symmetry of the {111} plane surface. An atomically stable two dimensional crystalline film resides on the epitaxial insulating layer with a coincident lattice match to the insulating interlayer. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
