Dependence of Mobility on Density of Gap States in Organics by GAMEaS - Gate Modulated Activation Energy Spectroscopy
W. So, D. V. Lang, V. Y. Butko +3
We develop a broadly applicable transport-based technique, GAte Modulated activation Energy Spectroscopy (GAMEaS), for determining the density of states (DOS) in the energy gap. GA…
Recent high-magnetic-field studies of unusual groundstates in quasi-two-dimensional crystalline organic metals and superconductors
J. Singleton, N. Harrison, R. McDonald +5
After a brief introduction to crystalline organic superconductors and metals, we shall describe two recently-observed exotic phases that occur only in high magnetic fields. The fir…
Landau quantization effects in the charge-density-wave system (Per)(mnt) (where Au and Pt)
R. D. McDonald, N. Harrison, J. Singleton +4
A finite transfer integral orthogonal to the conducting chains of a highly one-dimensional metal gives rise to empty and filled bands that simulate an indirect-gap semiconduc…
Absence of field-induced charge-density wave states in (Per)Pt(mnt)
R. D. McDonald, N. Harrison, P. Goddard +2
Graf {\it et al.} [Phys. Rev. Lett. {\bf 93} 076406 (2004)] recently attributed features in the magnetic-field-dependent longitudinal resistance of (Per)Pt(mnt) to a cascad…
Amorphous-like Density of Gap States in Single Crystal Pentacene
D. V. Lang, X. Chi, T. Siegrist +2
We show that optical and electrical measurements on pentacene single crystals can be used to extract the density of states in the HOMO-LUMO bandgap. It is found that these highly p…
Bias-Dependent Generation and Quenching of Defects in Pentacene
D. V. Lang, X. Chi, A. M. Sergent +1
We describe a defect in pentacene single crystals that is created by bias stress and persists at room temperature for an hour in the dark but only seconds with 420nm illumination.…
