We use plane-wave density functional methods to model Ge-Se-Ag-Cu liquids and glasses. The models are analyzed for structural and electronic properties and transition metal ion dynamics. Electronic properties are analyzed with the electronic density of states and projected density of states. The optical gap increases with increasing Ag content and decreases with increasing Cu content. We carry ...
Electric-field control of ferromagnetism in magnetic semiconductors at room temperature has been actively pursued as one of the important approaches to realize practical spintronics and non-volatile logic devices. While Mn-doped III-V semiconductors were considered as potential candidates for achieving this controllability, the search for an ideal material with high Curie temperature (T(c)>300 ...
We have investigated the thermoluminescent response and fading characteristics of germanium- and aluminium-doped SiO(2) optical fibres. These optical fibres were placed in a solid phantom and irradiated using 6 and 10 MV photon beams at doses ranging from 0.02 to 0.24 Gy delivered using a linear accelerator. In fading studies, the TL measurements were continued up to 14 days post-irradation. We...
