Abstract
We study the electron transport in semiconducting nanocrystal arrays at temperatures , where is the charging energy for a single grain. In this temperature range, the electron transport is dominated by cotunneling processes. We discuss both elastic and inelastic cotunneling and show that for semiconducting nanocrystal arrays, the inelastic contribution is strongly suppressed at low temperatures. We also compare our results with available experimental data.
