نبذة تعريفية / مختصر السيرة الذاتية

Welcome to website of Prof. Abdullah Aldwayyan. I hope you will find some thing useful. Hopping also to get some feed back from you. 
 

مجالات الخبره

I got my PhD degree in “Instabilities of Semiconductor Lasers” from Wales University (Cardiff), UK. my research expertise and interests include the fabrication and characterization of photonics devices including LEDs, LASERs, and Solar Cells. I work on the physical properties of new photovoltaic and lasing materials.
