This application discloses an AlGaInP red micro-LED chip with a high Al composition polarization-induced barrier layer and its fabrication method. The core innovation lies in the use of an Al composition in the barrier layer of the quantum well structure. x2 Ga 1‑x2 ) y2 InP gradually changes to Al 0.5 In 0.5 The high Al composition structure of P elevates the valence band level to 250-320 meV, significantly enhancing carrier confinement capability. Simultaneously, the barrier layer employs low-concentration p-type doping, inducing the formation of a three-dimensional hole gas through the polarization effect of the gradual Al composition change, allowing the hole concentration to break through the doping limit and avoiding the luminescence quenching problem caused by high doping. This solves the core problems of insufficient carrier confinement, low hole injection efficiency, and poor high-temperature stability in existing red Micro-LED chips. The device's external quantum efficiency, high-temperature retention rate, and long-term reliability are all significantly improved. The fabrication process is compatible with existing production lines and is applicable to multiple fields.

This application relates to a method, system, device, and medium for decomposing ultra-large-scale graph matrices. The method adaptively determines the upper limit of the spectral interval by extracting the degree distribution and community structure of the graph, and constructs a Chebyshev filter accordingly to filter the initial vector to amplify the target feature gap. Using the filtered vector as the starting block, block Lanczos iteration is performed to obtain Ritz values ​​and approximate eigenvectors. Convergence is determined based on the Ritz value gap and residuals. When stagnation occurs, the spectral interval is dynamically corrected based on the Ritz value distribution, and the filter is reconstructed. The approximate eigenvectors are then filtered again to restart the process, forming an estimation-filtering-convergence closed loop. Thus, the online spectral interval estimation, Chebyshev acceleration, and deep block Lanczos work together to suppress spectral radius overflow and eigenvector pseudo-alignment caused by extreme eigenvalues, overcoming convergence stagnation and achieving stable and efficient large-scale graph decomposition.
