Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites

open access: yesAdvanced Optical Materials, Volume 14, Issue 14, 10 April 2026.
ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

Microstrip patch array antenna

open access: yesElectronics Letters, 1984
A microstrip array with mutual coupled rectangular patch radiators is described. By the avoidance of a corporate feeding network, advantages in the antenna performance and design are realisable. Experimental results are presented for both linearly and circularly polarised antennas which demonstrate the usefulness of this special antenna configuration.
