Light effect in photoionization of traps in GaN MESFETs [PDF]

open access: yesPapers in Physics, 2009
Trapping of hot electron behavior by trap centers located in buffer layer of a wurtzite phase GaN MESFET has been simulated using an ensemble Monte Carlo simulation.

Carbon dioxide baited trap catches do not correlate with human landing collections of Anopheles aquasalis in Suriname [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 2011
Three types of carbon dioxide-baited traps, i.e., the Centers for Disease Control Miniature Light Trap without light, the BioGents (BG) Sentinel Mosquito Trap (BG-Sentinel) and the Mosquito Magnet® Liberty Plus were compared with human landing ...

Electron spin resonance from NV centers in diamonds levitating in an ion trap [PDF]

open access: goldNew Journal of Physics, 2017
We report observations of the electron spin resonance (ESR) of nitrogen vacancy centers in diamonds that are levitating in an ion trap. Using a needle Paul trap operating under ambient conditions, we demonstrate efficient microwave driving of the ...

Photoluminescence and thermoluminescence in a Li2SO4 crystall

open access: yesEurasian Journal of Physics and Functional Materials, 2022
The nature of intrinsic emission and the creation of electron-hole trapping centers in irradiated with ultraviolet and X-rays at 15 K and 300 K was investigated in Li2SO4 by methods of spectroscopy. It is shown that in activated Li2 SO4 with an energy of

A handmade trap for malaria mosquito surveillance by citizens in Rwanda

open access: yesPLoS ONE, 2022
For effective sampling of mosquitoes in malaria surveillance programmes, it is essential to include attractive cues in traps. With the aim of implementing a citizen science project on malaria vectors in rural Rwanda, a handmade plastic bottle trap was ...

Mechanisms for the creation of intrinsic electron-hole trapping centers in a CaSO4 crystall

open access: yesEurasian Journal of Physics and Functional Materials, 2021
The mechanism of creation of electron-hole trapping centers in CaSO4 at 15-300 K was investigated by the methods of vacuum-ultraviolet and thermoactivation spectroscopy. It is shown that electron-hole trapping centers are formed upon trap of electrons in
