Charge-transfer crystallites as molecular electrical dopants.

Nat. Commun. 6 , 8560, (2015)

Ground-state integer charge transfer is commonly regarded as the basic mechanism of molecular electrical doping in both, conjugated polymers and oligomers. Here, we demonstrate that fundamentally diff...

Freezing-in orientational disorder induces crossover from thermally-activated to temperature-independent transport in organic semiconductors.

Aharonov-Bohm oscillations in a quasi-ballistic three-dimensional topological insulator nanowire.

Nat. Commun. 6 , 7634, (2015)

Aharonov-Bohm oscillations effectively demonstrate coherent, ballistic transport in mesoscopic rings and tubes. In three-dimensional topological insulator nanowires, they can be used to not only chara...
