Stretching Livens Up Electron Transport

Molecular dynamics simulation shows boost in electron tunneling for elongated designer molecule
Department: Science & Technology
Keywords: electron tunneling, molecular dynamics, molecular electronics

As some molecules elongate, it turns out that they have an easier time transporting electrons along their frameworks, according to a molecular simulation study (J. Am. Chem. Soc., DOI: 10.1021/ja205908q). This counterintuitive behavior—longer molecules usually have poor conductance compared with shorter ones—could open the door to mechanically activated molecular electronic devices, says the research team led by Mark A. Ratner and George C. . . .
