Sketch of the electronic interactions inside a quantum material that result in a strange metal. Credit: Paul Neves By tinkering with a quantum material characterized by atoms arranged in the shape of a sheriff’s star, MIT physicists and colleagues have unexpectedly discovered a new way to make a state of matter known as a strange […]
Design of the SHiP experiment. Credit: Leiden University After many years of preparations, CERN has approved a new experiment: the Search for Hidden Particles (SHiP). Physicist Alexey Boyarsky was involved from the start. “We know there is physics that’s missing and we aim to find it.” “Ultimately, we try to capture the whole universe in […]
They took the idea of driving an LED via a hybrid-T network, which combine ac and dc drive signals, one stage further, building a capacitively-coupled ac control electrode onto a conventional GaN LED structure. The control electrode alters the number of holes in the p-GaN – Al2O3 region (see diagram), which varied from around 1016/cm3 […]
Operation is over 3.6 to 28V, with reduced function up to 42V, and the drvices have been developed with functional safety in mind. “The device is developed compliant to ISO 26262, meeting all process requirements for ASIL-C, and hardware architectural metrics for ASIL-B according to ISO-26262-10:208E, clause 9”, the company told Electronics Weekly. Processing comes […]
May 3, 2024 — According to Bloomberg analysts, Intel and Nvidia’s chip upgrades are expected to drive sales of TSMC’s 3nm chip process starting in the second half of the year. Shipments are expected to triple in 2024 and double again in 2025. Analysts pointed out that TSMC’s N3 process is the most advanced node currently […]
May 3, 2024 — According to NXP Semiconductors’ first quarter 2024 financial report, its revenue for the quarter was US$3.13 billion, with a gross profit margin of 58.2% and an operating profit margin of 34.5%. In the first quarter, NXP’s industrial and Internet revenue was US$574 million, a year-on-year increase of 14%; mobile business revenue was […]
Zinc oxide (ZnO) is a common ingredient in sunscreen lotions. Less well-known is the fact that it’s also a wide band gap (WBG) semiconductor (3.4 eV). As a nanomaterial, ZnO is being used to develop a wide variety of sensor technologies. Sensor applications for ZnO include health monitoring, chemical sensing, biomedical, and environmental sensors. Some […]
