GoKawiilResearchers report semiconductor with record 7-electronvolt bandgap
Writing in Nature, Steele and colleagues describe a semiconductor material whose electronic bandgap exceeds 7 electronvolts, the largest reported for any semiconductor. This value places the material in a range of electronic properties previously associated only with insulators.
GoKawiil's interpretation of the reporting above, not reported fact.
A larger bandgap allows materials to withstand higher voltages and temperatures without breaking down, which could make such semiconductors attractive for demanding power electronics applications. The achievement suggests the long-standing boundary between semiconductors and insulators is less fixed than assumed, potentially opening new directions for material design.
- A semiconductor with a bandgap over 7 eV has been reported, the highest on record.
- The result blurs the traditional distinction between semiconductors and insulators.
- Large-bandgap materials are valued for high-voltage and high-temperature electronic devices.
