We present a predictive and general approach to investigate near-field energy transfer processes between localized defects in semiconductors, which couples first-principles electronic structure calculations and a nonrelativistic quantum electrodynami

Rare-earth ion dopants in solid-state hosts are ideal candidates for quantum communication technologies, such as quantum memories, due to the intrinsic spin–photon interface of the rare-earth ion combined with the integration methods available in t

Direct‐write vapor deposition is a new technique that would enable one‐step 3D maskless nanofabrication on a variety of substrates. A novel silicon chip‐based microevaporator is developed that allows evaporant to exit through 2000–300 nm nozz

Abstract The exchange of ions across interfaces is key to the field of iontronics, where the properties of the device can be altered by the local ion concentration. This study investigates a complex oxide system where structural and electronic phase

The limited recovery speed of the single-photon avalanche diodes due to the passive resistor in series strongly reduces the detector’s frequency response. Here Zheng et al., overcome this problem by using an adaptive resistive switch and reaching a

Entangled photons can be used to create a truly secure communication link between two parties. However, the distance over which this can be achieved is limited by the transmission losses associated with optical fibers. One potential solution is using

Wireless Underground Sensor Networks (WUSNs) that collect geospatial in situ sensor data are a backbone of internet-of-things (IoT) applications for agriculture and terrestrial ecology. In this paper, we first show how WUSNs can operate reliably unde

Rare-earth ions (REIs) have incomplete 4f shells and possess narrow optical intra-4f transitions due to shielding from electrons in the 5s and 5p orbitals, making them good candidates for solid-state optical quantum memory. The emission of Er3+ in th

How does the price of energy affect the extent of production fragmentation in India’s manufacturing industries? The prevailing literature has engaged with production fragmentation and trade in middle products for a long time, but the relationship b
