Pentacene islands grown on ultra-thin SiO2
B. R. Conrad, W. G. Cullen, B. C. Riddick +1
Ultra-thin oxide (UTO) films were grown on Si(111) in ultrahigh vacuum at room temperature and characterized by scanning tunneling microscopy. The ultra-thin oxide films were then…
Spatial First-passage Statistics of Al/Si(111)-(root3 x root3) Step Fluctuations
B. R. Conrad, W. G. Cullen, D. B. Dougherty +2
Spatial step edge fluctuations on a multi-component surface of Al/Si(111)-(root3 x root3) were measured via scanning tunneling microscopy over a temperature range of 720K-1070K, fo…
Effect of Impurities on Pentacene Thin Film Growth for Field-Effect Transistors
Elba Gomar-Nadal, Brad R. Conrad, William G. Cullen +1
Pentacenequinone (PnQ) impurities have been introduced into a pentacene source material at number densities from 0.001 to 0.474 to quantify the relative effects of impurity content…
Effect of impurities on pentacene island nucleation
B. R. Conrad, Elba Gomar-Nadal, W. G. Cullen +3
Pentacenequinone (PnQ) impurities have been introduced into a pentacene source material in a controlled manner to quantify the relative effects of the impurity content on grain bou…
Percolative Effects on Noise in Pentacene Transistors
B. R. Conrad, W. G. Cullen, W. Yan +1
The 1/f noise in pentacene thin film transistors has been measured as a function of device thickness from well above the effective conduction channel thickness to only two conducti…
