20_08/2008Cover Picture: Reversible Conductance Switching in Molecular Devices (Adv. Mater. 8/2008)

The cover shows a photograph of molecular junctions as processed on a wafer being irradiated with a green laser to optically switch the single molecular layer of photochromic diarylethenes sandwiched between two electrodes. Bert de Boer and co-workers report on p.1467 that these reliable and reproducible solid-state molecular electronic devices, which show bidirectional conductance switching of molecular origin, can be produced using conventional processing techniques.
