Origin of Periodic Modulations in the Transient Reflectivity Signal at Cryogenic Temperatures
Salahuddin Khan, Rama Chari, J. Jayabalan +5
Periodic modulations that appear in the low-temperature transient reflectivity signal of a GaAsP/AlGaAs single quantum well is studied. Similar anomalous oscillations are also obse…
