Example Embodiment
[0018] The technology of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0019] Such as figure 1 , 2 As shown, in the method for determining the first initial side surface of the fly-cut single crystal germanium two-dimensional six-sided drum of the present invention, the steps of the method are:
[0020] S1. Cut out the upper and lower parallel reference planes of the single crystal germanium cylindrical bar grown along the single crystal germanium crystal plane, figure 1 Among them, 1 shows the upper datum plane of the single crystal germanium cylindrical bar, and the bar has enough cutting allowance;
[0021] S2. Roughen the end surface of the upper datum plane 1 of the single crystal germanium cylindrical bar to show anisotropic periodic petal distribution characteristics;
[0022] S3. After roughing the end surface, take the radial centerline 2 of any white-spotted petals on the surface (the surface morph...
