WebA lateral phototransistor structure based on mechanically exfoliated multilayer black arsenic (b-As) is produced to test its in-plane anisotropy of photoelectrical properties. First, the morphology and structure of the b-As flake are investigated with respect to light polarization and crystal structure orientation. Then, the Raman modes, demonstrating a strong … WebFeb 5, 2024 · Abstract Non-layered two-dimensional (2D) lead-free all-inorganic perovskites nanoplates have recently attracted considerable attention in photodetectors; however, the in-depth investigation of thickness on photodetection performance is still lacking. In this work, by constructing the famous metal-semiconductor-metal photodetectors, the …

WebMay 6, 2024 · The strategy of attaining efficient broadband photodetection in this work is the synthesis of suitable chromophores and waveguide matrices, which is of great importance. On the one hand, the ... WebFeb 17, 2024 · InAs nanowires have been considered as good candidates for infrared photodetection. However, one-dimensional geometry of a nanowire makes it unsuitable for broadband light absorption. In this work, we propose and design InAs nanosheet arrays to achieve polarization-independent, angle-insensitive, and ultrawide infrared absorption. the villages fl building department
