The detection is based on measuring the coherent spin dynamics of electrons, allowing us to distinguish the type of carrier in the QD core (electron or hole). We find that although initially negative photocharging happens because of fast hole trapping, it eventually evolves to positive photo...
In 1841 Fox Talbot patented his negative/positive process as the “Calotype.” He was then able to sell licenses in England, France, and America, sometimes marketed as Talbotype. Ultimately, however, Talbot’s efforts to maintain patent control over the negative/positive process failed, despite ...

positive film, slide film, and transparency film. All of these are the same names for a film that produces a ‘positive’ image. This means when you hold the processed film up to the light, you can see the finished image without needing to scan it digitally or print it on photographic ...
Thin layers of semi-conductor material, doped to PIN or NIP photoconducting layers, located above MOS and/or CMOS pixel circuits produce an array of layered photodiodes. Positive and negative charges produced in the layered photodiodes ... H Tzu-Chiang - US 被引量: 62发表: 2004年 Quality ...
A positive-working imaging element is described comprising a support coated first with a negative-working, solvent-developable, photohardenable stratum, then over-coated with a second negative-working, solvent-developable, photohardenable stratum; the second stratum serves as a mask for the first ...
