Bedair received PhD from UC Berkeley, published more than 300 refereed paper, cited more than 6670 times (h-index 45) and supervised 50 PhD students
His research has been devoted to finding new and novel approaches to producing high-efficiency solid-state devices that can replace low-efficiency devices now in common use. He is the inventor of the multi-junction solar cell, which has had a major impact upon the development of next generation photovoltaics. All satellite and space communication electrical systems are currently powered by the MJ solar cell, pioneered by Bedair.
He has also made significant contributions in the area of light-emitting diodes and solid state lighting (SSL). These devices are rapidly evolving and are now used in a variety of applications ranging from white light sources to flat panel displays for television, instruments.
His research also involves the development of advanced devices for the field that is now called ‘spintronics’. The goal of this research is to develop a new class of electronic devices that make use of the electron spin, rather than electron charge. This approach permits very low power electronic devices for applications such as solid-state memories for integrated circuits to be realized. He was the first to demonstrate that the ferromagnetic properties of magnetic semiconductors at room temperature.
He also pioneered the process for layer-by-layer growth of monolayers of atoms (or species) in a self-controlled limiting mechanism. This process is currently called Atomic Layer Deposition or Epitaxy (ALD or ALE). This is a materials-deposition process where chemistry is used in a creative manner to limit growth to one atomic layer at a time, the ultimate control for Nano structures. An ALD process are now widely used in integrated circuits technology to fabricate devices, such as capacitors for energy storage, is also widely used to form protective and wear-resistant coatings on such varied technologies as textile fabrics and implants.
Bedair was awarded several prizes such as Holliday medal award, Kuwait award in the field of energy, JR Reynold and Department of energy award.
