This study discusses the optical characteristics of Ultra-High-Brightness LEDs (UHB-LEDs) at high current density. The wafer bonding technique was applied in this research to enhance the light extraction efficiency of AlGaInP UHB-LEDs. This technique can replace the GaAs substrate with transparent substrates for achieving the high quantum efficiency. However, the structure that designed for light...
This paper shows a practical approach to GaN-based HEMT self-consistent electro-thermal simulation based on spectral-element method (SEM). The method is proposed to solve the heat transport equation in GaN-Based HEMTs. The high-order basis functions employed are orthogonal, leading to a diagonal mass matrix and a more sparse stiffness matrix. So the updating of thermal field is fully explicit when...
In this study, a dynamic elastic-plastic finite element model is used to simulate the bone temperature rise during drilling process. Various rotating speeds and applied forces of the drill bit are investigated to explore the effects of these parameters on the temperature rise within the bone. The results indicate that a drill bit with a higher rotating speed or a higher applied force can have noticeable...
This study develops an analysis method which can be applied to simulating the temperature rise during bone drilling. A three-dimensional dynamic elastic-plastic finite element model is used to simulate the process of a Kirschner pin drilling through a bone. The results indicate that lowering the initial temperature of Kirschner pin can decrease the temperature rise as well as the size of the thermal...
