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 […]

OXFORD PV PEROVSKITE SOLAR CELL ACHIEVES 28 EFFICIENCY

OXFORD PV PEROVSKITE SOLAR CELL ACHIEVES 28% EFFICIENCY

Oxford PV’s 1 cm2 perovskite-silicon tandem solar cell has achieved a 28% conversion efficiency, certified by the National Renewable Energy Laboratory. The achievement edges out Oxford PV’s own previous certified record of 27.3% efficiency for its perovskite-silicon solar cell, announced earlier this year. Dr Chris Case, Chief Technology Officer at Oxford PV commented, Today’s record demonstrates the unprecedented

WATER SPLITTING WITH SOLAR ENERGY

WATER SPLITTING WITH SOLAR ENERGY

Using solar energy to split water provides an efficient way for large scale renewable energy conversion and storage. A group of researchers from TUDelft and AMOLF have successfully developed an efficient and stable photo-electrode that could improve water splitting with solar energy. This photoelectrode absorbs light and directly decomposes water into hydrogen and oxygen. In addition to the efficiency, the system is

Counting bits in hardware reverse engineering the silicon in the ARM1 processor

Counting bits in hardware: reverse engineering the silicon in the ARM1 processor

How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor
