(DURIP) MBE SYSTEM UPGRADE FOR GROUP-IV ALLOYS AND OTHER EMERGING COMPOUND SEMICONDUCTORS FOR HETEROVALENT INTEGRATION
Abstract
The invention of epitaxial growth techniques, semiconductor heterostructures and superlattices has opened up tremendous opportunities for the development of materials that have vast applications in electronics and optoelectronics, such as IR imaging and sensing. Many heterostructures and superlattices, comprised of isovalent alloys and structures such as GaAs-AlGaAs and InAs-GaSb-InSb have been thoroughly studied and are widely used in many DoD and commercial applications. The proposed equipment will enable the creation of an innovative MBE growth system that can grow SiGeSnPb and many other different materials like II-VI and IV-VI binaries and alloys, which can all be monolithically integrated as heterovalent and quantum structures. The main objective of this DURIP is to upgrade an existing MBE system to enable it to support a newly awarded AFOSR MURI program to study SiGeSnPb alloys, including material growth, bulk and interface defects, and device applications. This MBE system will also be used to grow a large number of II-VI, III-VI, IV-VI compound semiconductors and their heterovalent and hetero-crystalline quantum structures. This machine is a unique MBE system in the US, in that it can integrate so many dissimilar compound semiconductors monolithically in one growth chamber. In addition to the MURI program, the system will support other ongoing and potential research programs at ASU as well as collaborating universities and research institutions funded by AFOSR, AFRL, ARO, NSF, DARPA and many industrial partners. The proposed machine will also be used extensively to train and support dozens of PhD students and postdocs over the next 10 - 15 years, and it will also strengthen our collaborations with government labs like AFRL, ARL, NVL, and other US universities and industry.
