Typically in the range of 10-15 picoseconds. This means that after a photon is absorbed by the GaAs material, it takes approximately 10-15 picoseconds for the electron to scatter and lose its energy before emitting a new photon. This scattering time is an important parameter in determining the performance of GaAs-based devices such as lasers, photodetectors, and solar cells. A shorter scattering time typically leads to faster device operation and higher efficiency.
