TL;DR: Results on formaldehyde detection using fluctuation-enhanced gas sensing showed that formaldehyde was easily detected via intense fluctuations of the gas sensor's resistance, while the cross-influence of ethanol vapor was negligible.

TL;DR: In this paper, a computer optimization was used to show that 70 nm of CoAl 2 O 3 (58 vol% Co) antireflection coated with Al 2 O3, deposited onto Ni, can yield a s ≈ 0.95 and e T ⪅ 0.1 even without composition grading or surface roughening.

TL;DR: In this paper, a study on 1/f noise in electrochromic (EC) devices undergoing discharge via a resistor was conducted, and it was shown that the noise was mainly associated with the Ni oxide, and measurements on individual parts of an EC device indicated that the 1/ f noise originated from localized areas.

TL;DR: Graphene has high mobility and optical transparency, in addition to flexibility, robustness and environmental stability as discussed by the authors, and its true potential lies in photonics and optoelectronics, where the combination of its unique optical and electronic properties can be fully exploited, even in the absence of a bandgap, and the linear dispersion of the Dirac electrons enables ultrawideband tunability.
Abstract: The richness of optical and electronic properties of graphene attracts enormous interest. Graphene has high mobility and optical transparency, in addition to flexibility, robustness and environmental stability. So far, the main focus has been on fundamental physics and electronic devices. However, we believe its true potential lies in photonics and optoelectronics, where the combination of its unique optical and electronic properties can be fully exploited, even in the absence of a bandgap, and the linear dispersion of the Dirac electrons enables ultrawideband tunability. The rise of graphene in photonics and optoelectronics is shown by several recent results, ranging from solar cells and light-emitting devices to touch screens, photodetectors and ultrafast lasers. Here we review the state-of-the-art in this emerging field.
