Transient THz conductivity of silicon with optical pumping above and below the second indirect transition
Fabio Novelli, Jeffrey A Davis
Here we perform a series of time-resolved experiments where a 100 fs pump pulse is tuned between 528 nm and 555 nm, across the second indirect gap of intrinsic silicon at ~540 nm w…
Revealing and Characterizing Dark Excitons Through Coherent Multidimensional Spectroscopy
Jonathan O. Tollerud, Steven T. Cundiff, Jeffrey A. Davis
Dark excitons are of fundamental importance in a broad range of contexts, but are difficult to study using conventional optical spectroscopy due to their weak interaction with ligh…
Two-dimensional double-quantum spectroscopy: peak shapes as a sensitive probe of carrier interactions in quantum wells
Jonathan O. Tollerud, Jeffrey A. Davis
We identify carrier scattering at densities below which it has previously been observed in semiconductor quantum wells. These effects are evident in the peakshapes of 2D double-qua…
