Light-induced electron spin resonance in amorphous hydrogenated germanium

We report the observation of light-induced electron spin resonance ~LESR! in amorphous hydrogenated germanium. Two new lines with zero crossings near g52.01 and g52.03 were detected and ascribed to electrons and holes in the conductionand valence-band-tail states, respectively. The ratio between the LESR spin densities of both lines is approximately one, suggesting the absence of spin pairing, ...

Watercress (Nasturtium officinale R. Br.) Minimally Processed: Effect of Storage Temperature and Different Films of Packaging

Watercress is a leafy vegetable of the family Brassicaceae that grows in and around water, it has a short shelf life (approximately seven days) and it is consumed raw or steamed. The objective of this work was to study the effect of packaging film and different storage temperature on the postharvest quality of watercress minimally processed. Treatments were: packed with plain film (PD961EZ, 31m...

Effect of Post-Deposition Annealing On Hydrogenated Amorphous Silicon Thin Films Grown At High Power by Pecvd

The crystallization of hydrogenated amorphous silicon layers (a-Si:H) [1,2] deposited by plasma enhanced chemical vapor deposition (PECVD) is of great interest. Generally, laser or metals are used to induce crystallization in aSi:H films. We have found that films deposited at high rf power (> 0.2 W/cm2) by PECVD technique shows some crystallites embedded in a-Si:H matrix and their after its vac...

Interface-induced room-temperature ferromagnetism in hydrogenated epitaxial graphene.

We show ferromagnetic properties of hydrogen-functionalized epitaxial graphene on SiC. Ferromagnetism in such a material is not directly evident as it is inherently composed of only nonmagnetic constituents. Our results nevertheless show strong ferromagnetism with a saturation of 0.9μ(B)/hexagon projected area, which cannot be explained by simple magnetic impurities. The ferromagnetism is uniqu...
