Abstract

The invention discloses a method for controllable generation of quantum dots or quantum wires, which belongs to the field of preparation of low-dimensional quantum materials. The method comprises the following steps: arranging a substrate for growing the quantum dots or the quantum wires in solution with dissolved the quantum dots or the quantum wires and arranging an electrode which is in contact with the lower surface of the substrate on the bottom surface of the substrate; applying voltage between the solution and the electrode for forming a steady electric field so as to enable quantum dot or quantum wire material in the solution to settle in the position where the electrode is located on the substrate under the action of electric field force of the steady electric field and grow the quantum dots or the quantum wires on the substrate in the position corresponding to the electrode; and adjusting the position of the electrode to control the growth positions of the quantum dots or the quantum wires on the substrate. The method is simple to operate and good in controllable effect; and according to the method disclosed by the invention, controllable growth in any quantum dot or quantum wire position can be realized, and a foundation is laid for processing and manufacturing of quantum devices.

Description

technical field [0001] The invention relates to the field of quantum dot or quantum wire material preparation, in particular to a position-controllable method for growing quantum dots or quantum wires. Background technique [0002] Nanoparticles or nanowires are also called quantum dots or quantum wires in physics due to the obvious quantum effect when the size is 1 to 20 nanometers. Quantum dots or quantum wire arrays have extremely broad application prospects in areas such as surface light sources, displays, solar cells, and information storage. The positioning and preparation of quantum dots and quantum wires has formed a bottleneck problem for the preparation of quantum devices, and quantum devices are more widely used, such as quantum computers, biochips, nanorobots, etc. [0003] When preparing quantum dots or quantum wire materials, in most methods, the position of quantum dots or quantum wires is random and uncontrollable. The template method and photolithography m...
