Bidirectional Self-Folding with Atomic Layer Deposition Nanofilms for Microscale Origami

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Baris Bircan, Marc Z. Miskin, Robert J. Lang, Michael C. Cao, Kyle J. Dorsey | Summary: Origami design principles are scale invariant and enable direct miniaturization of origami structures provided the sheets used for folding have equal thickness to length ratios. Recently, seminal steps have been […]

Spectral and spatial isolation of single WSe$_2$ quantum emitters using hexagonal boron nitride wrinkles

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Raphaël S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]

Extent of Fermi-surface reconstruction in the high-temperature superconductor HgBa$_2$CuO$_{4+δ}$

Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Mun K. Chan, Ross D. McDonald, Brad J. Ramshaw, Jon B. Betts, Arkady Shekhter | Summary: High magnetic fields have revealed a surprisingly small Fermi-surface in underdoped cuprates, possibly resulting from Fermi-surface reconstruction due to an order parameter that breaks translational symmetry of the crystal lattice. […]
