Preparation method of composite nanofiltration heterostructure capable of generating quantum dots on side wall of nanowire

The invention discloses a preparation method of a composite nanofiltration heterostructure capable of generating quantum dots on the side wall of a nanowire and relates to the field of nano engineering. An MOCVD device is applied to the preparation method. The preparation method comprises the flowing steps of depositing nano metal particles or metal film on an substrate, forming nano alloy particles after annealing, using the nano alloy particles as catalytic substances, generating the nanowire in the direction perpendicular to the substrate, ending the axial growth of the nanowire, and generating a single layer of quantum dots or multiple layers of the quantum dots on the side wall of the nanowire. Due to the adoption of the MOCVD device, the quantum dots directly grow on the side wall of the nanowire which is in a hexagonal-column shape, tedious steps of an existing preparation method are simplified, and the preparation cost is reduced. Meanwhile, due to the fact that film covers the quantum dots, wherein the film and the nanowire are made of the same materials, the multiple layers of the quantum dots can generate on the side wall of the nanowire, and the obtained composite nanofiltration heterostructure is made to be better. Therefore the preparation method of the composite nanofiltration heterostructure capable of generating the quantum dots on the side wall of the nanowire has a broad application prospect in a new generation of nano photoelectronic devices.

AP configuration modification method for achieving automatic connection and synchronization between AP and STA

The invention discloses an AP service terminal configuration modification method for achieving automatic connection and synchronization between an AP service terminal and an STA client. The method comprises the following steps: an AP configures a hidden service set identifier (SSID) and a key; factory settings of an STA are to automatically connect the SSID of the AP in a default manner; the STA is connected to the AP, then establishes a link connection, and then requests to synchronously display wireless configurations of the AP; and the STA breaks the connection with the hidden SSID after receiving SSID configurations displayed by the AP, and reconnects the displayed SSID configurations according to the own settings. According to the AP service terminal configuration modification method disclosed by the invention, the STA can be automatically connected to the AP, and when users modify the wireless configurations of the AP, the STA of terminal equipment can achieve automatic synchronization and connection after the AP modifies the configurations. By adopting the method, the complicated steps of the connection of wireless network settings can be simplified, and a plug and play mode and a fool-type automatic configuration mode can be achieved.
