Embodiment 1

[0031] In order to solve the problems of complex procedures, difficult preparation and time-consuming preparation of existing chiral structures, the present invention provides a triangular chiral structure, which includes a first right-angled side 1, a second right-angled side 2, and a third oblique side connected end to end. Side 3, the width of the third hypotenuse 3 is greater than or equal to the sum of the widths of the first right-angled side 1 and the second right-angled side 2, and the triangular chiral structure has good elementary dichroic characteristics, and can detect two different frequencies Light produces very good circular dichroism.

[0032] It should be noted that, if figure 2 As shown, the three sides of the triangular chiral structure satisfy l≥2d, wherein, l is the width of the third hypotenuse 3, and d is the width of the two right-angled sides, so that it can be ensured that the following two coatings will be on the third There is a coating on the hyp...

Abstract

The invention relates to a triangular chiral structure, comprising a first right-angled side, a second right-angled side, and a third hypotenuse connected end to end, and the width of the third hypotenuse is greater than or equal to the sum of the widths of the first right-angled side and the second right-angled side ; The brand-new triangular chiral structure, the chiral structure has good meta-dichroic properties, can produce good circular dichroic properties for light of two different frequencies, and the preparation method of this triangular chiral structure, There is no need to repeatedly perform processes such as glue rejection, electron beam exposure, development, and fixation, which saves many steps involved in the overlay process and eliminates possible errors in the overlay process. It is only necessary to adjust the direction and angle of the coating to prepare a triangular chiral structure with a height difference. It is very convenient to prepare a triangular chiral structure, which reduces the requirements for electron beam exposure technology and reduces the number of electron beam exposures.

Description

technical field [0001] The invention belongs to the field of metal structure preparation, and in particular relates to a triangular chiral structure and a preparation method thereof. Background technique [0002] Chirality is used to represent the symmetry of structures and has important meanings in many disciplines. Chirality refers to the property that an object cannot be superimposed on its mirror image, just like the left hand and right hand are mirror images of each other and cannot be superposed. Chirality is a basic feature in the process of life, and most of the organic molecules that constitute life are chiral molecules. [0003] Researchers use artificial chiral structures to study the mechanism of chirality generation and as sensor devices for detecting chirality. Therefore, it is very important to prepare chiral structures. When preparing a chiral structure with a height difference, it is necessary to prepare it by electron beam etching and electron beam vacuum...
