ELDRS and dose-rate dependence of vertical NPN transistor
bipolar junction transistor ELDRS effect dose-rate dependence
2009/8/17
The enhanced low-dose-rate sensitivity (ELDRS) and dose-rate dependence of vertical NPN transistors are investigated in this article. The results show that the vertical NPN transistors exhibit more de...
Displacement damage dose approach to analyze ion irradiation effects on homemade GaAs/Ge solar cells
GaAs/Ge solar cells displacement damage dose carbon ion proton irradiation
2009/8/14
Displacement damage dose is applied to analyze the irradiation effects of 2 MeV carbon ions and 0.28~20 MeV protons on homemade GaAs/Ge solar cells. The NIEL for each ion is modified by taking into a...
Rotating wheel filter design and optimization for a uniform depth dose distribution in heavy ion therapy
heavy ion spread-out Bragg peak rotating wheel filter Monte Carlo method
