Devices and methods for electrochemical liquid phase epitaxy

Electrochemical liquid phase epitaxy (ec-LPE) processes and devices are provided that can form precipitated epitaxial crystalline films or layers on a substrate. The precipitated films may comprise a semiconductor, such as germanium, silicon, or carbon. Dissolution into, saturation within, and precipitation of the semiconductor from a liquid metal electrode (e.g., Hg pool) near an interface region with a substrate yields a polycrystalline semiconductor material deposited as an epitaxial film. Reactor cells for use in an electrochemical liquid phase epitaxy (ec-LPE) device are also provided that include porous membranes to facilitate formation of the precipitated epitaxial crystalline films.

A self-aligned tunable metamaterial is formed as a wire mesh. Self-aligned channel grids are formed in layers in a silicon substrate using deep trench formation and a high-temperature anneal. Vertical wells at the channels may also be etched. This may result in a three-dimensional mesh grid of metal and other material. In another embodiment, metallic beads are deposited at each intersection of the mesh grid, the grid is encased in a rigid medium, and the mesh grid is removed to form an artificial nanocrystal.

High-throughput crystallographic screening device and method for crystalizing membrane proteins using a sub physiological resting membrane potential across a lipid matrix of variable composition

The invention is a high-throughput voltage screening crystallographic device and methodology that uses multiple micro wells and electric circuits capable of assaying different crystallization condition for the same or different proteins of interest at the same of different voltages under a humidity and temperature controlled environment. The protein is solubilized in a lipid matrix similar to the lipid composition of the protein in the native environment to ensure stability of the protein during crystallization. The invention provides a system and method where the protein is transferred to a lipid matrix that holds a resting membrane potential, which reduces the degree of conformational freedom of the protein. The invention overcomes the majority of the difficulties associated with vapor diffusion techniques and essentially reconstitutes the protein in its native lipid environment under cuasi physiological conditions.
