Growth and characterization of dilute magnetic semiconductors for spintronic devices.GROWTH AND CHARACTERIZATION OF DILUTE MAGNETIC SEMICONDUCTORS FOR SPINTRONIC DEVICES: Dilute magnetic semiconductors (DMS (1) (Document Management System) See document management. (2) (Defense Messaging System) An X.500-compliant messaging system developed by the U.S. Dept. of Defense. ) are ferromagnetic Refers to a material, such as iron and nickel, that can be easily magnetized. See MRAM. semiconductors recently discovered in nitride- and oxide- based semiconductor materials Semiconductor materials are insulators at absolute zero temperature that conduct electricity in a limited way at room temperature (see also Semiconductor). The defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties . They are created by incorporating a small percentage of magnetic atoms into the semiconductor host. DMS have received much attention recently due to their potential use in novel spintronic (spin + electronic) devices, ranging from electro-optical switches to qubits for quantum computing quantum computing Experimental method of computing that makes use of quantum-mechanical phenomena. It incorporates quantum theory and the uncertainty principle. Quantum computers would allow a bit to store a value of 0 and 1 simultaneously. . The ultimate success of the field of spintronics depends on materials with large spin polarization. Fortunately, DMS materials have 100% spin polarization. Therefore, the growth of high quality thin films of DMS materials, their property characterization, and an understanding of the science of these materials are very important in spintronics research. This presentation will discuss our recent research activities including; growth of high quality thin films using pulsed laser deposition, structural characterization, and magneto-transport and optical properties studies of DMS materials. * Robertson, B., G.
