Ever thinner solar cells
Thickness reduction can be a key element in the quest for cheaper and more efficient solar cells. Making solar cells at least 10 times thinner than commercial ones would save material, reduce manufacturing costs, and enable new …

Experimental quantification of atomically resolved HAADF-STEM images using EDX
High-angle annular dark field (HAADF) images acquired in a scanning transmission electron microscope (STEM) contain a wealth information on the structure and chemical composition of semiconductor crystals down to the atomic level. To date, …

Versatile Photonic Entanglement Synthesizer in the Spatial Domain
Abstract Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top bulk setups, but will presumably rather resort to integrated optics. Sequential bulk opticslike proposals based on cascaded …

Phase Transition in a Memristive Suspended MoS2 Monolayer Probed by Opto-and Electro-Mechanics
In recent years, new 2D semiconductor materials have shown exotic and exciting electronic or optoelectronic properties with multiple applications. In particular, several interesting mechanisms can hybridize in the same device. We have develop …

Quantum state engineering in arrays of nonlinear waveguides
Abstract In the current quest for efficient and experimentally feasible platforms for implementation of multimode squeezing and entanglement in the continuous variable regime, we underpin and complement our results on the generation of versatile multimode …
