Step 2: Characterize the 1D stack using STACK Optical Solver In this step we simulate the electronic and optoelectronic figures of merit, such as the IV curve, spontaneous emission power spectrum, and internal quantum efficiency.ĬHARGE/MQW coupled solver ensures self-consistent coupling between bulk semiconductor domains with solutions of the drift-diffusion and Poisson’s equations solved by CHARGE and quantum well active domain with solutions of the Schrödinger equation solved by MQW using k.p method. Step 1: Simulate the micro-LED using Coupled CHARGE/MQW Solvers
We will also use the STACK optical solver to characterize the emission properties of a planar device, and FDTD to simulate a 3D micro-LED. Here we will use the CHARGE/MQW self-consistently coupled solvers to simulate the IV curve, spontaneous emission power spectrum, and quantum efficiency. They require a large number of simulations and some post-processing is needed to analyze the devices' performance. Similar to OLEDs, micro-LEDs are challenging devices to simulate. Understand the simulation workflow and key results The STACK and FDTD are used to characterize and extract the emitted power and radiation pattern. The self-consistently coupled CHARGE and MQW solvers are used to calculate the \(I-V\) response, spontaneous emission power spectrum, and quantum efficiency. In this example, we simulate a micro-LED.
