Optimize Designs And Mitigate Thermal Threats In High-Current Automotive Applications


By Melika Roshandell, Cadence Design overview Current density increases at the PCB/package level result in local temperature increases known as hotspots. In addition to highlighting the heat generated locally around and underneath certain components at the PCB or IC package level due to component power consumption, the Celsius Thermal Solver can calculate the heat generated by the Joule ef... » read more

The Role of InGaN Quantum Barriers in Improving the Performance of GaN-based Laser Diodes


Abstract: "In this work, different aspects which have influences on device performance of blue laser diodes (LDs) when using InGaN instead of GaN as quantum barrier (QB) layers are investigated theoretically and experimentally. In the modeling calculation, it is found that the threshold current of LDs with InGaN QB layers is reduced obviously, but the slope efficiency is not largely improved... » read more
