Crystal growth method and solid-state component and apparatus for crystal growth employed therefor

A solid-state component for crystal growth wherein a crystal of a macromolecule is grown in grooves or holes holding a solution containing the macromolecule, said solid-state component comprising:

• at least two grooves or holes whose depths and/or widths of the opening parts differ from each other, and which are formed on one surface side of the opposed two principal surfaces, and
• a through hole for supplying a solution containing a macromolecule into said grooves or holes from the other surface side of said two principal surfaces, wherein
• valence electrons of said solid-state component are controlled so that the electrostatic property of the solid-state component in the surface part can be controlled in response to the environment of the solution containing the macromolecule, and
• said valence electrons are differently controlled between the inside portion and the outside portion of said grooves or holes.

An apparatus for crystal growth wherein a crystal of a macromolecule is grown in grooves or holes of a solid-state component holding a solution containing the macromolecule, said apparatus comprising:

• a plurality of solid-state components, whose valence electrons are controlled so that the electrostatic property of the solid-state components in the surface parts can be controlled in response to the environment of a solution containing a macromolecule, and which have at least two grooves or holes whose depths and/or widths of the opening parts differ from each other;
• and
• means for opposing said plurality of solid-state components to each other and holding the same with a prescribed clearance therebetween, wherein
• the valence electrons are differently controlled between the inside portion and the outside portion of said grooves or holes.
