Transport spectroscopy of disordered graphene quantum dots etched into a single graphene flake
D. Kölbl, D. M. Zumbühl
We present transport measurements on quantum dots of sizes 45, 60 and 80 nm etched with an Ar/O2-plasma into a single graphene sheet, allowing a size comparison avoiding effects fr…
Evidence for Disorder Induced Delocalization in Graphite
L. Casparis, A. Fuhrer, D. Hug +2
We present electrical transport measurements in natural graphite and highly ordered pyrolytic graphite (HOPG), comparing macroscopic samples with exfoliated, nanofabricated specime…
Breakdown of the Korringa Law of Nuclear Spin Relaxation in Metallic GaAs
D. Kölbl, D. M. Zumbühl, A. Fuhrer +2
We present nuclear spin relaxation measurements in GaAs epilayers using a new pump-probe technique in all-electrical, lateral spin-valve devices. The measured T1 times agree very w…
The Nuclear Spin Environment in Lateral GaAs Spin Valves
D. Kölbl, D. M. Zumbühl, A. Fuhrer +2
The spin degree of freedom in solids offers opportunities beyond charge-based electronics and is actively investigated for both spintronics and quantum computation. However, the in…
