Titanium Impurities in Silicon, Diamond, and Silicon Carbide
Since transition metal impurities affect the electronic and optical properties of semiconductors [1], it is important to understand the role of such unavoidable impurities on those properties. At the same time, transition metals in semiconductors can be used in other unusual situations. The energy levels related to transition metal impurities are aligned with respect to each other for the same ...
متن کاملEpitaxial diamond-hexagonal silicon nano-ribbon growth on (001) silicon
Silicon crystallizes in the diamond-cubic phase and shows only a weak emission at 1.1 eV. Diamond-hexagonal silicon however has an indirect bandgap at 1.5 eV and has therefore potential for application in opto-electronic devices. Here we discuss a method based on advanced silicon device processing to form diamond-hexagonal silicon nano-ribbons. With an appropriate temperature anneal applied to ...
متن کاملHigh Performance Power Diodes on Silicon Carbide and Diamond
Silicon Carbide and diamond Schottky barrier diodes (SBD) with an original and high efficiency termination are presented. The influences of termination parameters on the diodes electrical performance are investigated for both punch-through (PT) and non punch-through (nPT) structures by simulations. Design guidelines, based on simple analytical expressions, for ideal SBDs are included. Electrica...
متن کاملAnalytical Threshold Voltage Computations for 22 nm Silicon-on-Diamond MOSFET Incorporating a Second Oxide Layer
In this paper, for the first time, an analytical equation for threshold voltage computations in silicon-on-diamond MOSFET with an additional insulation layer is presented; In this structure, the first insulating layer is diamond which covered the silicon substrate and second insulating layer is SiO2 which is on the diamond and it is limited to the source and drain on both sides. Analytical solu...
