Influencing the conductance in biphenyl-like molecular junctions with THz radiation [PDF]
, 2013 We investigate the torsional vibrations in biphenyl-like molecular junctions and transport properties in the presence of an external THz field. Ab-initio calculations including external electric fields show that the torsional angle {\phi} of a thiolated ...

A generalised approach to torsionality maximisation in longitudinal-torsional ultrasonic devices [PDF]
, 2011 A longitudinal-torsional vibration mode has many applications in ultrasonic systems. Obtaining this behaviour could be achieved either by coupling the longitudinal and torsional modes or by degenerating the longitudinal mode, but the results may be ...
