Important results: experimentally observed for the first time and theoreticaley interpreted in Laue case were:
1) the phenomenon of complete and losses repumping of X-rays in quartz crystal from the direction of propagation to that of diffraction by excited acoustic oscillations or a thermal gradient
2) the phenomenon of focusing and defocusing of diffracted X-rays in piezocrystals in the presence of acoustic oscillations or a thermal gradient.
On the basis of this theory physical mechanisms were provided for the following earlier observed experimental facts:
- effect of the presence of saturation section on current-voltage characteristics of uniformly and locally deformed p-n junctions and Schottky diodes based on semiconductors of cubical symmetry, - effect of formation and vanishing of N-type negative differential conductivity (NDC) on inverse branches of the current-voltage characteristic of locally deformed germanium p-n junctions and Schottky diodes, and - effect of formation of sections of abrupt rise and fall of electric capacitance of such diodes if there exists N-type NCD on the current-voltage characteristics.
