DIY SILICON PHOTODIODE PARTICLE DETECTOR DIRECTLY FROM CERN

Silicon detectorsΒ are widely used in particle and nuclear physics for measuring ionizing radiation. This Do-It-Yourself project allows making a low-cost particle detector from scratch using silicon photodiodes. It can distinguish different particle types (alpha particles and electrons) and measures their energy between 33 keV and 8 MeV. The detector must be shielded from light and …

Terahertz Optical Transistors Beat Silicon

Terahertz Optical Transistors Beat Silicon

PORTLAND, Ore.–Purdue University researchers have demonstrated a CMOS-compatible all-optical transistor capable of 4THz speeds, potentially over a 1000 times faster than silicon transistors. Nano-photonic transistors processed at low-temperatures can be fabricated atop complementary metal oxide semiconductors (CMOS) to boost switching time by ~5,000-times less than 300 femtoseconds (fs) or almost 4 terahertz (THz), according to …

Silicon Carbide Substrate Boosts LED Luminosity

Silicon Carbide Substrate Boosts LED Luminosity

The majority of contemporary LEDs are constructed from a combination of Indium gallium nitride (InGaN) and sapphire substrate. The architecture works well and has allowed LED manufacturers to offer products exhibiting efficacies in excess of 150 lm/W. However, the architecture does have some drawbacks which have encouraged chipmakers to seek other options. One commercially successful …
