Phys. Rev. B 72, 073104 (2005) [4 pages]Mechanism of a molecular electronic photoswitch
Min Zhuang and Matthias Ernzerhof Received 25 January 2005; revised 14 April 2005; published 8 August 2005 We present a simple non-self-consistent method for the calculation of the molecular conductance under finite bias voltage. Our approach is applied to a molecular photoswitch that has recently been investigated in break junction experiments [D. Dulić et al., Phys. Rev. Lett. 91, 207402 (2003)]. We obtain I-V characteristics that are qualitatively in agreement with experimental measurements. Employing our electronic structure calculations, we provide a detailed explanation for the switching behavior observed in experiment. ©2005 The American Physical Society
