The bandgap is a major factor in determining the electrical properties of the underlying materials in microelectronic equipment. In general, materials with large bandgaps are insulators, whereas those with tiny bandgaps are excellent semiconductors. Ultrawide bandgap (UWB) semiconductors can function at substantially greater powers and temperatures than traditional silicon-based small-bandgap processors manufactured with mature bandgap substances like GaN (gallium nitride) and SiC, a more recent form of semiconductor technology (silicon carbide).
Ga2O3 (gallium oxide) is one of the most promising substances for ultra-wideband (UWB) applications, according to researchers at the Naval Research Laboratory (NRL), Florida State University (UF), and Korea University. 4.8 eV (Electron Volts) is a huge difference in bandgap between gallium oxide and silicon, which is 1.1 eV, and it goes even farther than the 3.3 eV of GaN and SiC.
At the Leibniz Supercomputing Centre, a team of TU Dresden researchers used the SuperMUC supercomputer to fine-tune their method for studying organic semiconductors. It uses a technique called semiconductor doping, which involves intentionally releasing contaminations into a material to enhance its semiconducting properties. Nature Materials just published its findings.
According to the team leader Dr. Frank Ortmann, organic semiconductors are being used in new device areas for the first time in the industry. While many of these are currently on the market, others are being held back by a lack of technical know-how. The limits of these semiconductors, as well as their individual efficiency, are being investigated through the use of doping techniques. Using these techniques, semiconductor characteristics may be fine-tuned.” A material’s electrical characteristics are influenced by the material’s physical properties when they are altered by someone else.
