Summary A single level dot At and the single level quantum dot exhibits a step around. Finite bias can split this step into 2 or 4 steps, depending on and. When there are 4 steps, a peak [dip] appears around for [ ]. Finite temperature smears the steps, but can turn the previous peak into a dip. 2 single level dots If, there is a dip / peak at. This dip oscillates with. Thank you!!!
