Microwave Irradiation Effects on Random Telegraph Signal in a MOSFET

open access: yes, 2006
We report on the change of the characteristic times of the random telegraph signal (RTS) in a MOSFET operated under microwave irradiation up to 40 GHz as the microwave field power is raised.

High order fractional microwave induced resistance oscillations in 2D systems

open access: yes, 2009
We report on the observation of microwave-induced resistance oscillations associated with the fractional ratio n/m of the microwave irradiation frequency to the cyclotron frequency for m up to 8 in a two-dimensional electron system with high electron ...

Effects of ultraviolet-C and microwave irradiation on the expression of heat shock protein genes in the maize weevil (Coleoptera: Curculionidae)

open access: yesEuropean Journal of Entomology, 2016
The maize weevil, Sitophilus zeamais (Motschulsky), is a major pest of stored grain kernels. Irradiation is an established technique for controlling insects in stored grain and is a major stress factor affecting these insects.

FASTER PLASTICIZERS PRODUCTION BY MICROWAVE IRRADIATION

open access: yesProceedings 17th International Conference on Microwave and High Frequency Heating, 2019
Plasticizers are esters used to confer plasticity to polymer goods. They are prepared by esterification between a carboxylic acid or anhydride and a heavy alcohol. Esterification is a very slow reaction and its batches may last more than 12 hours of processing [1].

Dynamic Nuclear Polarization in Silicon Microparticles [PDF]

open access: yes, 2008
We report record high Si-29 spin polarization obtained using dynamic nuclear polarization in microcrystalline silicon powder. Unpaired electrons in this silicon powder are due to dangling bonds in the amorphous region of this intrinsically heterogeneous ...
