Systems for Optoelectrics Effect

Optoelectronics is the study of the quantum mechanical effects of light on semiconductor materials within the presence of an electric field. Electronic devices that source, detect and control light are used in order the study these quantum effects. Among such devices are light emitting diodes (LEDs), semiconductor lasers, solar cells, photodiodes, and charged-coupled imaging devices (CCDs), which require both the manipulation of light and the electric field.

For this type of application, Janis Research offers researchers a range of optical cryostats using either liquid nitrogen/helium or cryogen-free cooling, covering the temperature range from 1.5 K – 500 K (800 K optional). A wide range of window materials is available to cover the spectral region from ultraviolet (UV) to near-infrared (NIR) to far-infrared (FIR). To introduce the electric field to the optoelectronic device, various types of hermetically sealed electrical feedthroughs can be installed (such as multipin [8-,10-, 19-, 32- pin], BNC, SMA, and triaxial.) Janis can also install wiring from the electrical feedthroughs using single stranded wires, coaxial/triax cables, or semi-rigid coaxial cables. In addition, Janis Research offers a variety of sample holders for different types of samples used in optoelectronics. Available sample holders include:

  • 8-pin resistivity
  • Fixed 4-probe
  • DIP socket 
  • LCC chip carrier
  • Cuvette

Almost any cryostat with windows and electrical feedthroughs can be used for optoelectrics effect experiments. Our cryogenic systems guide may help you determine which system is best for your particular experimental requirements. Or contact Janis today and a sales/application engineer will assist you.
