pseudomorphic การใช้

• Fossils are often formed by pseudomorphic replacement of the remains by mineral matter.
• Bertrandite often occurs as a pseudomorphic replacement of beryl.
• In 1992 he was promoted to Laboratory Manager, overseeing the invention of a pseudomorphic high electron mobility transistor.
• Originally, MMICs used High Electron Mobility Transistors ( HEMTs ), Pseudomorphic HEMTs and Heterojunction Bipolar Transistors have become common.
• It was used with indium gallium arsenide to make a record breaking pseudomorphic heterojunction bipolar transistor that could operate at 604 GHz.
• Commonly found with and as coatings on chalcocite, chalcopyrite, bornite, enargite, pyrite, and other sulfides, it often occurs as pseudomorphic replacements after other minerals.
• It was shown to be an effective method for modelling and designing AlGaAs / GaAs HEMTs and the important pseudomorphic high electron mobility transistors ( pHEMTs ) based on InGaAs / GaAs systems.
• If they are near-lattice-matched the device is "'pseudomorphic "', and if the layers are unmatched ( often separated by a thin buffer layer ) it is "'metamorphic " '.
