Subsequently, p-type-doped GaN with Mg is coated on the outside of the MQW to form a capping film. The structure and preparation process are shown in Figure 19a. The emission wavelength of the core/shell GaN nanowire LED is controlled by an external voltage, just like a multi-active QW...
A 60 W SWIPT prototype with a full-duplex communication rate of 20 kbps is built to verify the proposed method. Keywords: bidirectional power transmission; crosstalk; FSK; full-duplex information transfer; infor- mation transfer channel gain; SWIPT 1. Introduction Based on convenience and safety,...
