Phys. Rev. B 75, 052302 (2007) [4 pages]Transport properties of semiconducting nanocrystal arrays at low temperaturesSee Also: Publisher's Note Received 29 September 2006; revised 18 December 2006; published 8 February 2007; corrected 12 February 2007 We study the electron transport in semiconducting nanocrystal arrays at temperatures T⪡Ec, where Ec 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. © 2007 The American Physical Society URL:
