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 ...

A research team in South Korea has developed a next-generation sensor material capable of integrating the detection of multiple light wavelengths. A joint research team led by Dr. Wooseok Song at the ...

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

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.

(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 ...

An optical/electric dual-mode photodetector array for human–machine collaborative infrared imaging was demonstrated. The responsivity of the photothermoelectric photodetector was improved by the ...

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 ...

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 ...

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 ...
