We report the growth of ultrathin single-crystal ZnO nanobelts by using a Ag-catalyzed vapor transport method. Extensive transmission electron microscopy and atomic force measurements reveal that thickness is ∼ 2 nm. Scanning post-growth annealing studies suggest '1D branching 2D filling' process. Our results demonstrate critical role catalyst in deterministic synthesis nanomaterials with desired morphology. In addition, these ultrafine exhibit stable field emission unprecedented high...
5G mm-wave systems in the frequency-range-2 (FR2) band (ranging from 24.25 to 43.5GHz) are expected provide multi-gigabit-per-second (mGb/s) data-rates. Different FR2 bands employed build wireless networks different countries/regions around world. Thus, a broadband/multiband economically support international/cross network roaming.

However, operating temperature of previously reported CSIPs has been limited below 30 K. In this work, we propose a technique that enhances above liquid nitrogen by dynamically controlling electrostatic potential optical floating gate (FG). This control effectively suppresses annihilation photogenerated...
