High-performance face-to-face integrated stacked QLED

2025-07-16 15:55

Quantum dot light-emitting diodes (QLEDs), through the lamination technology of vertically integrating multiple light-emitting units, can theoretically achieve a linear increase in device brightness and efficiency, bringing revolutionary opportunities to ultra-high-definition displays and solid-state lighting fields.

Hyperspectral channel density on-chip diffractive speckle spectrometer

Driven by the demand for high-performance miniature spectrometers, research on chip-scale spectrometers is continuously breaking through towards high integration, high resolution, and large bandwidth. This work proposes a silicon-based on-chip spectrometer based on cascaded disordered metasurfaces. Through various on-chip wavefront modulation mechanisms, high-spectral speckle is generated, which expands the number of spectral channels with a compact chip size, thus achieving extremely high on-chip spectral channel density and providing an effective means for achieving high-resolution, large-bandwidth spectral detection.

Research progress on the high quantum efficiency mechanism of type-II superlattice infrared detectors

Type-II superlattice (T2SL) infrared detectors offer high sensitivity and fast response speeds, making them suitable for long-range imaging and high-speed moving target tracking. Quantum efficiency (QE) is a key indicator of the ability of a photoelectric detector to produce high-quality images, and improving the QE of T2SL infrared detectors is of great significance.
