Supersonic molecular beam deposition (SuMBE) is a thin film growth method for organic semiconducting molecules that gives unprecedented control on morphology and structure by tuning the kinetic energy of the impinging molecules. This is the key factor by which we could control the growth of high quality films showing state of the art electrical properties for pentacene films. We show that exploiting such ability to control structure and morphology of the films one could tailor the gas response of the organic thin film transistors. We envisage the potential of such devices in applications where the transistor configuration offers new strategic opportunities as in gas sensing and in microfluidics. © 2007 Elsevier Ltd.

Abstract
Supersonic molecular beam deposition (SuMBE) is a thin film growth method for organic semiconducting molecules that gives unprecedented control on morphology and structure by tuning the kinetic energy of the impinging molecules. This is the key factor by which we could control the growth of high quality films showing state of the art electrical properties for pentacene films. We show that exploiting such ability to control structure and morphology of the films one could tailor the gas response of the organic thin film transistors. We envisage the potential of such devices in applications where the transistor configuration offers new strategic opportunities as in gas sensing and in microfluidics. © 2007 Elsevier Ltd.
