The present invention relates to solvothermal vapor synthesis methods for the crystallization of a phase from a mixture of selected inorganic or organic precursors in an unsaturated vapor-phase reaction medium.

Embodiments of the disclosure an apparatus for solvothermal crystal growth, comprising: a pressure vessel having a cylindrical shape and a vertical orientation; a cylindrical heater having an upper zone and a lower zone that can be independently controlled; at least one end heater; and an inward-facing surface of a baffle placed within 100 millimeters of a bottom end or top end surface of the growth chamber. The end heater is configured to enable: a variation in the temperature distribution along a first surface to be less than about 10° C., and a variation in the temperature distribution along a second surface to be less than about 20° C., during a crystal growth process. The first surface has a cylindrical shape and is positioned within the pressure vessel, and the second surface comprises an inner diameter of the growth chamber, and the temperature distribution along the second surface is created within an axial distance of at least 100 millimeters of an end of the growth chamber proximate to the first surface.

Various articles and devices can be manufactured to take advantage of a what is believed to be a novel thermodynamic cycle in which spontaneity is due to an intrinsic entropy equilibration. The novel thermodynamic cycle exploits the quantum phase transition between quantum thermalization and quantum localization. Preferred devices include a phonovoltaic cell, a rectifier and a conductor for use in an integrated circuit.

Devices, systems and methods for fabricating semiconductor material devices by placing a batch of wafers in a chemical solution within a growth chamber. The wafers are held in a vertical direction and are actuated to move within the chemical solution while growing a layer over exposed surfaces of the wafers.
