In today's rapidly developing quantum technology, the preparation and performance optimization of single photon sources, as the core cornerstone of quantum computing, quantum communication, and quantum sensing, have always been the focus of scientific research. Hexagonal boron nitride, with its unique advantages of no surface dangling bonds and bright single photon emission at room temperature, has become an ideal substrate for preparing solid-state single photon sources.

To achieve high-precision preparation, stable screening, and performance control of single photon sources in hexagonal boron nitride, the core requirement of precise manipulation at the microscale cannot be avoided. The Xinming piezoelectric nano positioning platform is a key equipment in this research process, providing stable and high-precision positioning and scanning support for the experiment.

1、 The core challenge of hexagonal boron nitride research: precise manipulation at the microscale

The core of hexagonal boron nitride single photon source lies in the atomic level defects inside the material, which are usually in the nanometer scale. To effectively study them, the first prerequisite is to accurately locate and lock the target defects.

In the study of hexagonal boron nitride single photon sources, strict requirements are placed on accuracy and control stability at every step from sample characterization to performance testing: observing the luminescence distribution of defects in hexagonal boron nitride, or testing the spectrum of single photon sources point by point, all require precise laser focusing on the nanoscale defect area.

In addition, in the testing, continuous tracking of individual luminescent points should be achieved to ensure the accuracy of photon signal acquisition. Even in the subsequent screening of stable single photon sources, it is necessary to compare and characterize samples with inconsistent states in the same region to avoid the influence of positioning deviation on experimental results.

These requirements happen to be the core advantages of the Xinming piezoelectric nanopositioning platform: with nanometer level motion accuracy and excellent stability, it can provide micro level stroke and nanometer level precision control solutions for the research of hexagonal boron nitride single photon sources.

2、 Key application scenarios of tomorrow's piezoelectric nano positioning platform

In the experimental process of preparing a single photon source for hexagonal boron nitride and studying its luminescence stability, the Xinming piezoelectric nano positioning platform was deeply involved in the core steps of sample characterization and performance testing, ensuring the reliability of experimental data through precise manipulation.

1. Fluorescence scanning imaging

In the preparation process of hexagonal boron nitride single photon source, researchers need to observe the luminescence of defects through fluorescence scanning confocal microscopy. Among them, the Xinming piezoelectric nano positioning platform plays the role of accurately moving samples:

·It can drive the sample to achieve automated scanning in a two-dimensional plane, covering the entire sample area required for the experiment;

·The nanometer level motion accuracy ensures the positional accuracy of each scanning point, avoiding missed or misjudgment of luminescent points due to positioning deviation.

By relying on the high-precision scanning of the piezoelectric nano positioning platform, researchers can quickly identify which regions of hexagonal boron nitride defects have potential single photon emission characteristics, which can narrow down the scope and accurately and quickly locate them for subsequent experiments.

2. Single point positioning test

When there is an evolutionary pattern in the target structure due to differences in dosage, researchers need to conduct refined testing on individual targets, such as measuring, verifying their characteristics, and so on. In this process, the precise positioning ability of the chip tomorrow's piezoelectric nano positioning platform is crucial:

·It can accurately move the target points on the sample one by one to below the microscopic focus, ensuring accurate measurement of the luminescence of individual targets;

·In long-term testing, the high stability of the piezoelectric nano positioning platform can effectively suppress drift, ensuring the continuity and reliability of signal acquisition;

·In conjunction with the program, it can also achieve linkage with the counting module required for the experiment, automate the testing of multiple objectives one by one, and greatly improve experimental efficiency.

3、 Characteristics of Tomorrow's Piezoelectric Nanopositioning Platform
