Article Synopsis
- * SiC nanocrystals were synthesized for the first time through pyrolysis of organosilane CHSi at high pressure and temperatures, allowing for sizes to range from ~2 nm to ~500 nm by adjusting the temperature.
- * The research reveals how changing growth techniques and heat treatment can influence both the crystal size and optical properties, making these materials suitable for infrared photonics applications.
