Wavelength dependence of nitrogen vacancy center charge cycling

Physical Review B
Optically-active spin qubits in wide-bandgap semiconductors exist in several charge states, though typically only specific charge states exhibit desirable spin or photonic properties. An understanding of how interconversion between different charge states occurs is important for most applications seeking to employ such defects in quantum sensing and ...

Statistical investigations on nitrogen-vacancy center creation

, 2018
Quantum information technologies require networks of interacting defect bits. Color centers, especially the nitrogen vacancy (NV-) center in diamond, represent one promising avenue, toward the realisation of such devices.

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Coupling of a single nitrogen vacancy center to the gap modes of a dual silver nanowire system

, 2012
We couple a nitrogen vacancy center in a diamond nano-crystal to a dual silver nanowire system by positioning the crystal in the gap between the two nanowires, and demonstrate a lifetime decrease of 8 ...

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

Advanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.
