摘要:
An electromechanical device is described which will abruptly remove growing crystals from melts in order to preserve interfacial detail. High initial acceleration, of the order of a thousand gravities, is provided by an impact mechanism. This acceleration, the subsequent travel, and the damping are adjustable, and the entire sequence is triggered electrically. Dendritic samples of germanium indicate preservation of interfacial detail on a scale of a few microns.
