Facilities
MBE Growth
The MBE laboratory at City College consists of a Riber 2300
P dual chamber MBE growth system with two interconnected MBE
chambers one for the growth of As-based III-V materials and
the other for the II-VI materials. The III-V chamber includes

is also available. The II-VI chamber has Cd, Zn, Mg, Be, Te,
Se , ZnCl2 and a Nitrogen rf-plasma source. The two chambers
are connected by UHV transfer modules. This allows the growth
of III-V buffer layers prior to II-VI deposition on InP or
GaAs substrates. A metal deposition chamber with an electron
beam evaporator is also part of the UHV system. The MBE is
housed in a class 100,000 clean room facility with a class
100 laminar flow hood for sample preparation.
In addition, we will receive within the next two months another
MBE growth system that will be set up for the growth of group
III-nitrides. This system is a donation from Northrup Grumman.
It is a dual chamber system consisting of a Riber 2300P MBE
