Which of the following option denotes the conditions in an Molecular beam epitaxy system?
Which of the following option denotes the conditions in an Molecular beam epitaxy system? Correct Answer Super cool temperatures
MBE is a technique for growing thin epitaxial structures on the substrate. MBE takes place in ultra high vacuum (10-8 to 10-12 torr), in the absence of carrier gases, resulting in high purity of the grown films. In solid source MBE high temperatures are required to sublime elements like gallium and arsenic to eventually condense them on to the substrate.
