Doping dependent charge injection and band alignment in organic field-effect transistors

B. H. Hamadani, H. Ding, Y. Hao +1

We have studied metal/organic semiconductor charge injection in poly(3-hexylthiophene) (P3HT) field-effect transistors with Pt and Au electrodes as a function of annealing in vacuu…

Magnetoresistance of atomic-scale electromigrated nickel nanocontacts

Z. K. Keane, L. H. Yu, D. Natelson

We report measurements of the electron transport through atomic-scale constrictions and tunnel junctions between ferromagnetic electrodes. Structures are fabricated using a combina…

Excitons in Carbon Nanotubes with Broken Time-Reversal Symmetry

S. Zaric, G. N. Ostojic, J. Shaver +10

Near-infrared magneto-optical spectroscopy of single-walled carbon nanotubes reveals two absorption peaks with an equal strength at high magnetic fields ( 55 T). We show that th…

Propagating Coherent Acoustic Phonon Wavepackets in InMnAs/GaSb

J. Wang, Y. Hashimoto, J. Kono +4

We observe pronounced oscillations in the differential reflectivity of a ferromagnetic InMnAs/GaSb heterostructure using two-color pump-probe spectroscopy. Although originally thou…

Kondo resonances and anomalous gate dependence of electronic conduction in single-molecule transistors

L. H. Yu, Z. K. Keane, J. W. Ciszek +5

We report Kondo resonances in the conduction of single-molecule transistors based on transition metal coordination complexes. We find Kondo temperatures in excess of 50 K, comparab…

Ultrafast Quenching of Ferromagnetism in InMnAs Induced by Intense Laser Irradiation

J. Wang, C. Sun, J. Kono +4

Time-resolved magneto-optical Kerr spectroscopy of ferromagnetic InMnAs reveals two distinct {\em demagnetization} processes -- fast ( ps) and slow (100 ps). Both compone…

Griffiths phase in the thermal quantum Hall effect

A. Mildenberger, F. Evers, R. Narayanan +2

Two dimensional disordered superconductors with broken spin-rotation and time-reversal invariance, e.g. with p_x+ip_y pairing, can exhibit plateaus in the thermal Hall coefficient…
