The main purpose of the VCCS in MBE applications is enhanced flux control and cracking of materials that are highly corrosive as a vapor. It was originally designed as a source for an antimony radical (Sb2) molecular beam as group V material in standard III-V MBE. The VCCS is also used for CdTe solar cell layer deposition. The all-PBN construction of the inner parts, the valve mechanism in particular, in combination with the flexibility provided by three independent heater circuits allows also the use of other materials like Te, Mg or Se with the VCCS. The large crucible capacity of 420 cc, fast and precise flux control and easy handling for maintenance and crucible refill make the VCCS an ideal source for smaller production MBE systems as well as for higher throughput
research MBE systems.
