Professor Yong-Hang Zhang's Group
The laboratory is equipped with three solid source MBE chambers for the growth of III-V semiconductor materials. All chambers are equipped for reflection high energy electron diffraction (RHEED) characterization and are fully computer controlled.
|
 |
VG V80H (Chamber A and B)
The other two chambers (chamber A and B) are VG V80H twin-chamber MBE systems. Both the machines are dedicated to the growth of GaAs, InP, GaSb, and InAs based optoelectronic devices; including laser diodes, light emitting diodes, optical refrigeration devices, photodetectors, and photovoltaic devices; with a wavelength ranging from 600 nm to 3 microns.

Temperature and power dependent
photoluminescence
The photoluminescence setup is currently equipped with a 50 mW HeNe Laser and a 100 mW semiconductor laser as the light source pump. A spectrometer equipped with a photo multiplier tube (PMT) and a Ge detector is capable of performing temperature photoluminescence measurements and other optical spectral measurements for wavelengths from 400 nm to 1700 nm, at temperature ranging from 8 K to 320 K. |
 |
Transmittance and reflectance measurement
A Fourier Transform Infrared Spectrometer (FTIR) equipped with an InGaAs detector, an InSb detector, and a MCT detector is capable of measuring transmittance and reflectance at wavelengths ranging from 1 micron to 25 micron. |
 |
Time resolved photoluminescence
A time resolved luminescence spectroscopy system is equipped with one GaAs PMT, one InGaAs PMT, and three MCT detectors to cover wavelength range from 0.3 microns to 12 microns. The system is capable of measuring time-resolved photoluminescence and electroluminescence from 10 K to 400 K with nano second resolution. |
