Linear field theories Linear field theories form the classical counterparts to many important QFT's in condensed matter physics, modeling a wide range of materials, from the mundane (semiconductors), to the exotic (topological insulators and superconductors). Linear field theories are exactly soluble, and, when quantized, form great first approximations to complicated QFT's. Non-interacting parti…

A new kind of light-emitting diode could one day produce more light while using less material. Researchers at Lund University in Sweden have developed an experimental LED made with extremely thin, branching nanowires. The design could potentially improve energy efficiency and reduce manufacturing costs. The research was published in the journal Nano Research. LEDs are […] The post Tiny Nanowires …

Scientists have developed a new lead-free solar material that can better survive exposure to air, moisture and heat. The advance could help make next-generation solar cells safer, more efficient and practical for everyday use. Perovskite solar cells have attracted worldwide interest because they can turn sunlight into electricity efficiently and may be easier and cheaper […] The post A Molecular …

Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that are strong but slow or fast but weak. The trade-off between signal strength and speed can limit precision detection. In new research, Stanford University researchers worked [&#82…

The investment supports growing semiconductor demand and strengthens local supply by year-end. The post Solvay Expands Electronic Grade Hydrogen Peroxide Capacity in Taiwan appeared first on Semiconductor Digest .

Lead halide perovskite light-emitting diodes (PeLEDs) have emerged as highly promising candidates for next-generation displays and solid-state lighting, achieving record-high external quantum efficiencies (EQEs) exceeding 30%. The perovskites possess outstanding optoelectronic properties, such as high photoluminescence quantum yields (PLQY), narrow full-width at half maximum (FWHM), and efficient…

MIT researchers have developed a way to produce silicon-photonics chips that are both flexible and transparent. The technology could eventually support curved augmented-reality displays, lightweight pilot visors and health-monitoring devices that fit closely against the body. Silicon photonics uses light instead of electrical signals to move and process information on computer chips. It has helpe…

Nature Electronics, Published online: 04 September 2026; doi:10.1038/s41928-026-01702-4 A layer of gallium oxide that is only a half-unit-cell thick can be converted via strain engineering into a zincblende phase with switchable ferroelectricity and a coercive voltage below 1 V.

As semiconductor designs advance toward trillion-transistor packages, the traditional engineering playbook of simply adding more personnel or running legacy software faster has hit a wall, a top Nvidia executive warned Tuesday.

Andrew Dzurak helped build silicon's first spin qubits at UNSW with Andrea Morello, then founded Diraq to make them on the chip industry's own production lines. In 2025 four foundry-made devices cleared 99 per cent fidelity, evidence at the level of a few qubits for a claim the company has to prove at the level of a machine.

MIT researchers have developed flexible, transparent silicon-photonics chips that could enable curved displays, wearable health monitors, and lighter optical systems for demanding new electronics applications. MIT researchers, working with NY Creates, have developed flexible, transparent silicon-photonics chips that could bring advanced optical systems to curved displays, wearable health monitors…

The chip resistors combine power handling, high-frequency operation, and low parasitics for a range of applications. Vishay Intertechnology, Inc. has introduced a new series of thin-film chip resistors in compact 0402 and 0603 case sizes. Built on an aluminium nitride (AlN) substrate, the Vishay Sfernice CHEP series combines power handling and high-frequency performance in standard […]

The field of silicon photonics, which uses light rather than electricity to transmit and process data on semiconductor chips, has enabled optical systems to evolve from bulky setups to compact, advanced systems. Typically, however, these silicon-photonics chips are rigid and opaque. MIT scientists have now figured out a scalable way to make silicon-photonics chips flexible […]

Researchers showed that an ultrathin, nanolayered boron nitride interlayer can improve the stability of perovskite quantum dot LEDs by passivating defects, suppressing ion migration, and enhancing heat dissipation. BN-optimized devices achieved an average peak EQE of 30.05% and a measured T50 lifetime of 102 hours at 2,000 cd m-2, with accelerated testing projecting a T50 of 25,263 hours at 100 c…

The Photovoltaic Research Department of the Korea Institute of Energy Research (KIER) achieved a certified world-record efficiency of 26.7% for perovskite/CIGS tandem solar cells, opening a new chapter in next-generation thin-film photovoltaics. This achievement was officially certified by the Fraunhofer Institute for Solar Energy Systems (ISE) in Germany and listed in the Best Research-Cell Effi…
