摘要
Electron relaxation and transport dynamics in low-temperature-grown GaAs under 1 eV optical excitation were investigated. Femtosecond transient transmission measurement and electro-optical sampling measurement in bulk samples and fabricated devices were used in the investigation. The results show that an increase in the electron lifetime can be observed when the electron density is higher than 3 × 1017 cm-3.
