Journal ArticleDOI
Spin Lifetimes Exceeding 12 ns in Graphene Nonlocal Spin Valve Devices
Marc Drögeler,Christopher Franzen,Frank Volmer,Tobias Pohlmann,Luca Banszerus,Maik Wolter,Kenji Watanabe,Takashi Taniguchi,Christoph Stampfer,Christoph Stampfer,Bernd Beschoten +10 more
TL;DR: It is demonstrated that the spin lifetime does not depend on the contact resistance area products when comparing all bottom-up devices indicating that spin absorption at the contacts is not the predominant source for spin dephasing.
Journal ArticleDOI
Nanosecond Spin Lifetimes in Single- and Few-Layer Graphene–hBN Heterostructures at Room Temperature
Marc Drögeler,Frank Volmer,Maik Wolter,Bernat Terrés,Bernat Terrés,Kenji Watanabe,Takashi Taniguchi,Gernot Güntherodt,Christoph Stampfer,Christoph Stampfer,Bernd Beschoten +10 more
TL;DR: In this paper, a new fabrication method of graphene spin-valve devices that yields enhanced spin and charge transport properties by improving both the electrode-tographene and graphene-to-substrate interface is presented.
Journal ArticleDOI
Nanosecond spin lifetimes in single- and few-layer graphene-hBN heterostructures at room temperature
Marc Drögeler,Frank Volmer,Maik Wolter,Bernat Terrés,Bernat Terrés,Kenji Watanabe,Takashi Taniguchi,Gernot Güntherodt,Christoph Stampfer,Christoph Stampfer,Bernd Beschoten +10 more
TL;DR: It is shown that room temperature spin transport in single-, bi-, and trilayer graphene devices exhibit nanosecond spin lifetimes with spin diffusion lengths reaching 10 μm combined with carrier mobilities exceeding 20,000 cm(2)/(V s).
Journal ArticleDOI
Nanosecond spin lifetimes in bottom-up fabricated bilayer graphene spin-valves with atomic layer deposited Al2O3 spin injection and detection barriers
Marc Drögeler,Frank Volmer,Maik Wolter,Kenji Watanabe,Takashi Taniguchi,Daniel Neumaier,Christoph Stampfer,Bernd Beschoten +7 more
TL;DR: In this paper, a spin transport study on bi-and trilayer graphene non-local spin-valves is presented, which have been fabricated by a bottom-up fabrication method.
