| Abstract: | The method of realizing STM-MBE quantum dot VGA waveform display and mark based on FPGA and Verilog HDL is proposed. The height data waveform of quantum dots growth-experiment is displayed in the VAG monitor by using the on-chip ROM of FPGA. The superiority of FPGA control and high efficiency of its image processing are utilized to realize the manual and automatic mark of all the oscillogram displayed in the VGA display,so as to analyze of pros and cons of quantum dots’ growth,and describe the surface morphology of the quantum dots. Better display result of quantum dot waveform was obtained in the experiment of the quantum dot waveform display. The arbitrary point in the oscillogram can be marked by manual or automatic operation. |
