Semi-Solid Metal Forming - A Process for Manufacturing

The following paper deals with the manufacturing of composite and hybrid materials by using semi-solid forming technologies. On the one hand, there is presented a process for producing Interpenetrating Phase Composites (IPC) consisting of ceramic open-cell structures which are infiltrated by a semi-solid aluminium alloy. On the other hand, a new process for manufacturing hybrid metallic

List of semiconductor materials - Wikipedia

Semiconductor materials are nominally small band gap insulators.The defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties in a controllable way. Because of their appliion in the computer and photovoltaic industry—in devices such as transistors, lasers, and solar cells—the search for new semiconductor materials and the

Development of a Novel Semi-Solid Metal Processing

Semi-solid metal (SSM) processing, invented more than 30 years ago at MIT [1], is a metal forming process that fills partially-solidified metal with globular structure in a mold, instead of casting with liquid metal. The characteristics of SSM are, for example, lower heat content than liquid metal, partially-solidified metal at the

Metal-Semiconductor Contacts

Metal-semiconductor contacts are an obvious component of any semiconductor device. At the same time, such contacts cannot be assumed to have a resistance as low as that of two connected metals. In particular, a large mismatch between the Fermi energy of the metal and semiconductor can result is a high-resistance rectifying contact.
