WebAs a result, the carrier mobility of the QD array in the low carrier density, weak external electric field regime is several orders of magnitude higher in the cis compared to the trans configuration. This is the first demonstration of mobility modulation using QDs and azobenzene that could lead to a new type of switching device. WebThe cis configuration is observed in the peptide bonds containing proline, because the free energy difference between cis and trans isomers is much smaller. Cis conformation peptide bonds can have an impact on protein structure and function. Cis-prolyl peptide bond surrogates were evaluated.
