Described is a method comprising directing an ultra-low voltage electron beam to a surface of a first insulating layer. The first insulating layer is disposed on a second insulating layer. The method includes modifying, by the application of the ultra-low voltage electron beam, the surface of the first insulating layer to selectively switch an interface between a first state having a first electronic property and a second state having a second electronic property.

Matter and energy are delivered by superimposing multiple quantum wave states such that composite wave amplitudes are maximized at delivery target points and/or minimized at designated intermediate points. One or more target locations are identified for delivery of matter or energy waves, analyzing the medium along the transit path from the emitters, calculating interaction probabilities at each point along the medium, creating a scoring system for optimizing and limiting thresholds of interaction in designated regions; and calculating a combination of wave frequencies, emitter locations and vectors such that quantum interference between the beams optimizes the scoring outcome. The scoring system may be used to reward amplitudes within a specified range over a specified volume of space and penalized if the amplitude falls outside the range. The combined beam may be used for various purposes, including without limitation biological or military target compromise or elimination, electrical energy delivery, etc.
