Hole mobility in organic single crystals measured by a “flip-crystal” field-effect technique

Abstract

-We report on single crystal high mobility organic field-effect transistors (OFETs) prepared on prefabricated substrates using a "flip-crystal" approach. This method minimizes technique employed in this study shows potential as a general method for studying charge transport in field-accumulated carrier channels near the surface of organic single crystals.2

Electronic transport properties of pentacene single crystals upon exposure to air

“…Pentacene is a good material for electronic devices like field effect transistors. [1][2][3][4][5][6][7][8] However, the results obtained by different research groups are not always consistent. This can be attributed in part to the fact that the performance of the devices depends critically on the environmental conditions.…”

Threshold voltage shift in organic field effect transistors by dipole monolayers on the gate insulator

“…Rubrene crystals were used because large planar crystals can be grown as described in e.g. [19], and because rubrene shows a very high mobility [53][19] [54]. The wafers were treated with (A) or (E) and the resulting transistors have a on/off ratios > 10 7 and a mobility > 1 cm 2 /Vs, indicating that the presence of the SAM has little or no influence on the effective mobility.…”

“…After finishing the treatment process, rubrene single crystals grown as described in [19] were carefully placed on the prepatterned structures completing the transistors. The measurement procedure was the same as for the thin film transistors.…”

A Polymorph Lost and Found: The High‐Temperature Crystal Structure of Pentacene

“…[2][3][4] The triclinic structure of crystalline pentacene was first reported in 1961. [5,6] However, this particular structure has not been reproduced in subsequent crystalgrowth experiments.…”
