Safa Kasap has made extraordinary contributions to the science and technology of amorphous semiconductors, in particular in pioneering engineering contributions to x-ray photoconductors used in modern digital flat panel direct conversion x-ray image detectors for medical imaging; and in advances in understanding excess noise in amorphous semiconductors. Professor Kasap is well-recognized for his distinct contributions to engineering education and training through two well-known textbooks, Principles of Electronic Materials and Devices (Third Edition) and Optoelectronics and Photonics: Principles and Practices with translations to other languages. He is the principal founder of the prestigious conference series International Conference on Optical, Optoelectronic and Photonic Materials (ICOOPMA).
