METHOD FOR GENERATION OF HIGH-ENERGY PHONONS IN LATTICE STRUCTURES Russian patent published in 1998 - IPC

FIELD: solid-body physics, acoustic systems, high-temperature superconductivity. SUBSTANCE: method involves application of permanent magnetic field, electric field, tension deformation to lattice structure of solid body in various combinations, driving this structure by means of alternating fields until high-energy phonons are generated which provide traveling three-dimensional and two-dimensional acoustic waves or superconducting state for (when ℏ︀ω_m>= kT) in conductors. Upper limit of phonon energy ℏ︀ε_m depends on value of permanent external field which alters both power of acoustic waves and superconductivity transition temperature θ_n as kθ_n= ℏ︀ω_m, where k and ℏ︀ are Boltzmann and Planck constants, ω_m is maximal height of phonons. EFFECT: increased functional capabilities. 2 cl, 2 dwg
