epitaxy |
Also found in: Wikipedia | 0.02 sec. |
epitaxyProcess of growing a crystal of a particular orientation on top of another crystal. If both crystals are of the same material, the process is known as homoepitaxy; if the materials are different, it is known as heteroepitaxy. Common types of epitaxy include vapour phase, liquid phase, and solid phase, according to the source of the atoms being arranged on the substrate. Epitaxy is most frequently employed in the production of semiconductor wafers for use in the creation of integrated circuits. epitaxy [′ep·ə‚tak·sē] (crystallography) Growth of one crystal on the surface of another crystal in which the growth of the deposited crystal is oriented by the lattice structure of the substrate.

| Cheng's presentation will be part of the "Mobility Enhancement Technology" session and includes a review of recent material technology advances; presenting a multiple set of approaches for future research in the area of heteroepitaxy on bulk silicon substrates. There, he spearheaded semiconductor research in diverse areas including thin-film optical coatings, photovoltaic solar cells, heteroepitaxy, wafer engineering, silicon and gallium arsenide electronic and photonic devices. As the leader of Lincoln Lab's Electronic Materials Group, he spearheaded semiconductor research in areas including thin-film optical coatings, photovoltaic cells, heteroepitaxy, wafer engineering, silicon and gallium arsenide electronic and photonic devices. |
