ZnO nanoleaves with high surface-to-volume ratio and more exposed polar facets produced via multistage hydrothermal synthesis showed photodetection properties.

We independently phase lock the repetition rates of two femtosecond lasers at their approximately 456, 000th harmonic to a common optical oscillator. The timing jitter of each individual laser relative to the optical reference is only 0.45 fs in a 100-Hz bandwidth. Our method takes advantage of the tremendous leverage that is possible when stability is transferred from the optical to the microw...

Today we will complete our two-lecture treatment of semiclassical versus quantum photodetection theory in continuous time, focusing our attention on the coherent detection scenarios of homodyne and heterodyne detection. As we did last time for direct detection, we will build these theories in a scalar-wave, quasimonochromatic framework in which there is no (x, y) dependence for the fields illum...

Surface plasmons (SPs) can be generated at the interface between two materials having opposite signs of dielectric susceptibility. [ 1 ] This principle has recently been exploited in many applications, ranging from enhanced optical transmission (EOT), [ 2 ] which can be used for enhanced photodetection, [ 3 ] biosensing, [ 4 ] optical trapping of small particles [ 5 ] and bacteria, [ 6 ] and ev...

Additive manufacturing of electronic devices using inkjet printing provides a potential alternative approach in substitution for conventional fabrication processes. However, the complex nature involves liquid deposition and film formation from vaporization solvent, which makes it different created by methods. Inkjet zinc oxide (ZnO), is widely utilized semiconductor, produces polycrystalline co...

Thin-film photodetectors built from one-dimensional nanostructures have attracted extensive attention due to their significance in basic scientific research and potential technological applications. It is still desirable to develop new materials with a wide response range for application in photodetectors. In this work, a Bi19S27I3 nanorod cluster film has been successfully fabricated on variou...
