Reconstitutable Nanoparticle Superlattices* [PDF]

Nano Letters, 2014
Colloidal self-assembly predominantly results in lattices that are either: (1) fixed in the solid state and not amenable to additional modification, or (2) in solution, capable of dynamic adjustment, but difficult to transition to other environments.

Modeling and Analysis of Noise Reduction Method in SPAD-Based LiDAR System

IEEE Photonics Journal, 2023
Ambient light interference stands as the primary source of noise encountered by the light detection and ranging (LiDAR) systems based on single-photon avalanche diode (SPAD), which seriously restricts the detection range and accuracy of sensors.

Type II superlattices for infrared detectors and devices [PDF]

, 1991
Superlattices consisting of combinations of III-V semiconductors with type II band alignments are of interest for infrared applications because their energy gaps can be made smaller than those of any 'natural' III-V compounds.
