title = "Carrier dynamics of electrons in n-type modulation-doped InAs/GaAs quantum dot structure studied using THz time-domain spectroscopy",
abstract = "We have investigated the carrier transport dynamics of n-type modulation-doped InAs/GaAs quantum dots (QDs) using terahertz time-domain spectroscopy (THz TDS) in order to estimate the total number of electrons captured by the QDs. The THz transmission of the sample with QDs is larger than that of the sample without QDs, which implies that the conductivity of sample with QDs is lower than that without QDs. From the THz waveforms and subsequent analysis, the density and mobility of free electrons, which are not captured by the QDs, have been obtained.",
