Optoelectronic Devices for In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...

Thin Film Stoichiometry and Defects Management for Low Threshold and Air Stable Near‐Infrared Perovskite Laser

open access: yesAdvanced Materials, EarlyView.
As defect density in 3D perovskites is controlled by adjusting excess formamidinium iodide concentration, shallow defects acts as a carrier sink for amplified spontaneous emission (ASE). A comprehensive charge carrier dynamic model is presented to understand the critical factor of the reduction of ASE threshold.
