- Description:
- Quantum wells are thin-layered structures used in the development of smaller and more efficient optoelectronic devices. In this project, we design and construct a room temperature photoluminescence setup to study exciton interactions in semiconductor quantum wells. An exciton is a bound state of electron and hole. The goal of this project is to study the interaction of quantum confined exciton states with surface states in free standing GaAs quantum wells by using photoluminescence spectroscopy. The free standing quantum well structure has a high surface to volume ratio. The study has potential applications to laser technology and sensor development to view biological and chemical species. It provides the capability to study adsorbate interaction, which is important for sensor technology.
