A new ultrathin photodetector captures light across the full spectrum in just 125 picoseconds, opening the door to faster, ...

The result is a very thin, yet very effective, light-absorbing photodetector -- a building block for the future of optoelectronics. "It is an enabling technology that allows you to look at a wide ...

Making an incredibly fast photodetector is one thing, but actually measuring its speed is another. Graduate student Haining Wang came up with an inventive way of measuring the near-instantaneous ...

Figure 1. A systematic diagram from material dimensions and patterning processes to device applications. Perovskite structure. Major patterning methods, including template-confined growth, inkjet ...

(Nanowerk Spotlight) In recent years, two-dimensional (2D) materials have attracted tremendous attention due to their exotic physical and chemical properties. So far, the main research enthusiasm has ...

Using graphene, one of science's most versatile materials, engineers have invented a new type of photodetector that can work with more types of light than its current state-of-the-art counterparts.

Scientists at IBM have used nano-engineering techniques to make the world’s fastest “avalanche photodetector”. Such devices are used in telecommunications networks and the work is an important advance ...

Researchers at IBM have made the first photodetector from graphene – a sheet of carbon just one atom thick. The device, which can accurately detect optical data streams at speeds of 10 Gbit/s, could ...

BUFFALO, N.Y. — In today's increasingly powerful electronics, tiny materials are a must as manufacturers seek to increase performance without adding bulk. Smaller also is better for optoelectronic ...
