6th group elements as dopants to silicon ?

Click For Summary
SUMMARY

The discussion focuses on the implications of using 6th group elements as dopants in silicon, highlighting their application in experimental infrared photovoltaics (IR PVs) and optical sensors. While these dopants can enhance certain properties, they may disrupt the crystal structure and introduce stability issues due to misaligned energy levels. Key references include studies from MIT and various scientific journals that detail the effects and challenges associated with these dopants.

PREREQUISITES
  • Understanding of semiconductor physics
  • Familiarity with doping processes in silicon
  • Knowledge of crystal structure and stability in materials science
  • Experience with infrared photovoltaic technology
NEXT STEPS
  • Research the effects of different dopants on silicon crystal structure
  • Explore the role of 6th group elements in enhancing infrared photovoltaic efficiency
  • Investigate stability issues related to dopant energy levels in semiconductors
  • Study experimental setups for testing optical sensors using doped silicon
USEFUL FOR

Researchers in semiconductor technology, materials scientists, and engineers working on photovoltaic systems and optical sensors will benefit from this discussion.

what will result when 6th group elements are used as dopants to silicon ?
 
Engineering news on Phys.org
It can work:

Seems to be mostly used for experimental IR PVs and optical sensors.

But it probably screws up the crystal structure, may put the dopant energy levels in an odd place and may have stability issues.
