Figure 1: Comparison of Superjunction transistor, SiC MOSFET, and GaN HEMT

The commercial availability of Superjunction transistors 20 years ago, challenged and finally proved wrong the limitations of conventional silicon-based transistors with respect to on-state resistance. What was regarded as revolutionary at that time is standard today. Today there is not a single transistor from 25

Access Fixtures Introduces a Versatile New LED Canopy Light
WORCESTER, Mass./PRNewswire/ -- Access Fixtures has introduced a budget-friendly canopy light called the SYRF which is available in both a round and a square design. SYRF is a fixture that flush mounts to ceilings and canopies at retail facilities, schools, hotels, hospitals, and any other similar commercial location. The SYRF boasts incredible value and efficiency at 22 lumens per dollar, and an L70 rated life of 147,000 hours, guaranteeing years of maintenance-free use. A smooth frosted polycarbonate lens emits light in a wide 110 degree beam spread and prevents glare, even when mounting from ceilings between 8 to 12 feet high. A durable die cast aluminum housing and vandal resistant one-piece lens prevents breakage or shattering. At 11.6 system watts, SYRF emits up to 75 lumens per watt, making it an incredibly efficient fixture. SYRF is low profile, m

Detraction-Free Light-Matter Interaction

Sven Scholz (left) and Arne Ludwig are experts for generating quantum dots in semiconductors.

Certain semiconductor structures, so-called quantum dots, might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons (light particles) emitted by the quantum dots transporting information across large distances. However, structures form by de

A Laser for Penetrating Waves

An international research team has been able to show that it is relatively easy to generate terahertz waves with an alloy of mercury, cadmium and tellurium.

The "Landau-level laser" is an exciting concept for an unusual radiation source. It has the potential to efficiently generate so-called terahertz waves, which can be used to penetrate materials as well as for future data transmission. So far, however, nearly all attempts to make such a laser reality ha

The Future of Perovskite-Based Light-Emitting Diodes

(A) Photoluminescence and (B) electroluminsecence in low-dimensional and 3D perovskite-based devices. Photoluminescence (PL) refers to the emission of light caused by the absorption of incident photons, whereas electroluminescence (EL) is the emission of light owing to the energy supplied by an electric current. Although low-dimensional perovskite exhibits better PL properties than 3D perovskite, the latter has better EL properties, which can be exploited to design very bright and efficient PeLEDs.

Scientists at Tokyo Institute of Technology discover a new strategy to design incredibly efficient perovskite-based LEDs with record-setting brightness by leveraging the quantum confinement effect. Several techniques for generation of light from electricity have been developed over the years. Devices that can
