Journal ArticleDOI
Precise control of thermal conductivity at the nanoscale through individual phonon-scattering barriers
Gilles Pernot,Mathieu Stoffel,Ivana Savic,Fabio Pezzoli,Peixuan Chen,Guillaume Savelli,A. Jacquot,Joachim Schumann,U. Denker,Ingolf Mönch,Ch. Deneke,Oliver G. Schmidt,Jean-Michel Rampnoux,Shidong Wang,M. Plissonnier,Armando Rastelli,Stefan Dilhaire,Natalio Mingo +17 more
TL;DR: By engineering a set of individual phonon-scattering nanodot barriers, this work accurately tailored the thermal conductivity of a single-crystalline SiGe material in spatially defined regions as short as approximately 15 nm, resulting in a room-temperature kappa well below the amorphous limit.
Journal ArticleDOI
Stretchable Graphene: A Close Look at Fundamental Parameters through Biaxial Straining
Fei Ding,Hengxing Ji,Yonghai Chen,Andreas Herklotz,Kathrin Dörr,Yongfeng Mei,Armando Rastelli,Oliver G. Schmidt +7 more
TL;DR: Tunable biaxial stresses, both tensile and compressive, are applied to a single layer graphene by utilizing piezoelectric actuators, unambiguously revealing that the 2D peak frequency (omega(2D)) is not exactly twice that of the D peak (omegas(D).
Journal ArticleDOI
A solid-state source of strongly entangled photon pairs with high brightness and indistinguishability.
Jin Liu,Rongbin Su,Yuming Wei,Beimeng Yao,Saimon Filipe Covre da Silva,Ying Yu,Jake Iles-Smith,Kartik Srinivasan,Armando Rastelli,Juntao Li,Xue-Hua Wang +10 more
TL;DR: In this article, an entangled photon pair source with high brightness and indistinguishability was presented by deterministically embedding GaAs quantum dots in broadband photonic nanostructures that enable Purcell-enhanced emission.
Journal ArticleDOI
On-demand generation of background-free single photons from a solid-state source
Lucas Schweickert,Klaus D. Jöns,Katharina D. Zeuner,Saimon Filipe Covre da Silva,Huiying Huang,Thomas Lettner,Marcus Reindl,Julien Zichi,Rinaldo Trotta,Rinaldo Trotta,Armando Rastelli,Val Zwiller,Val Zwiller +12 more
TL;DR: In this paper, the authors presented a solid-state source of on-demand single photons yielding a raw second-order coherence of g(2)(0)=(7.5±1.6)×10−5 without any background subtraction or data processing.
Journal ArticleDOI
Highly indistinguishable and strongly entangled photons from symmetric GaAs quantum dots
Daniel Huber,Marcus Reindl,Yongheng Huo,Huiying Huang,Johannes S. Wildmann,Oliver G. Schmidt,Armando Rastelli,Rinaldo Trotta +7 more
TL;DR: GaAs quantum dots can emit triggered polarization-entangled photons with high purity, which shows that GaAs might be the material of choice for quantum-dot entanglement sources in future quantum technologies.
