Figure 1: The absorption of a photon in a silicon nanocrystal excites an electron from the valence band (VB) to the conduction band (CB). The idea underpinning the team's approach is the ultrafast ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

As the laser beam is about 500-1000 nm in diameter, we can see single photon emission from an individual defect if the defect density is suitable. We start by engineering our materials at the atomic ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now ...

Abstract: More and more attention has been paid to the heterogeneous semiconductor device based on the wafer-bonding method due to its high-quality wafer-bonded active layer. In this paper, we first ...

Experiments: We report a miniature platform to manipulate model cell membranes in the form of droplet interface bilayers (DIBs), and non-invasively measure spatio-temporally resolved interfacial ...

Only one interstellar candidate, I1004,1,2, showed a track. The terminal particle has large enrichments in S, Ti, Cr, Mn, Ni, Cu, and Zn relative to Fe-normalized CI values. It has high Al/Fe, but ...
