Strain-induced InGaAs/InAlAs superlattices for terahertz radiation

D. S. Ponomarev, A. E. Yachmenev, S. S. Pushkarev +7

We study the influence of residual strain in InGaAs/InAlAs superlattice (SL) on the ultrafast photocarrier dynamics under femtosecond laser excitation. We propose and fabricate a n…
