Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations — virtual photons popping in and out of existence ...

Very high-speed MSM photodiodes have been fabricated on Er-doped GaAs over a doping range of 10/sup 18/-10/sup 20/ cm/sup -3/. The impulse response (characterized by photoconductive sampling) of these ...

Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers ...

Researchers from Kyoto Institute of Technology are claiming to have broken new ground by demonstrating the first vertical ...

A popular 2D active material, molybdenum disulfide (MoS2), just got a platinum upgrade at an atomic level. A study led by ...

The effect of p-type doping of the active region of multiple quantum-well (MQW) semiconductor optical amplifiers (SOAs) has been studied. Spectrogram measurements of the dynamics of the SOAs reveal ...

Molecular doping provides a route toward designing new organic compounds with improved performance for optoelectronics. Here, we investigate the p-type doping of crystalline diindenoperylene (DIP) ...

In inorganic semiconductors, doping is usually achieved by substituting impurity atoms into the crystal lattice. In organic materials, doping was first carried out using halogens and alkali metals as ...
