Influence of the Epitaxial Growth Conditions of the Active Region on the Performance of Far‐Ultraviolet‐C Light‐Emitting Diodes

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
Far‐ultraviolet‐C light‐emitting diodes emitting at emission wavelengths of 226 or 233 nm with active regions epitaxially grown under different conditions are compared regarding their emission power, operation voltage, and lifetime. Based on these optimizations, 226 nm LEDs with an L70 lifetime larger than 250 h and an initial emission power of more ...

Chipped-Stone Tools

2021
Guila Naquitz, a small microband camp, did not contain the full range of tools known for the preceramic; no one site of that period did. There is also at least one low ignimbrite mesa in the area that seems to have been used as a quarry for silicified material.
