  • Saw-toothed electrode and method for enhancing performance of nanowire UV detector
    Patent number: 11349036
    Abstract: The present invention discloses a saw-toothed electrode and a method for enhancing the performance of a nanowire UV detector, and relates to the field of semiconductor technologies. The saw-toothed electrode includes two symmetrically arranged patterns; the pattern includes a rectangle and multiple isosceles trapeziums; lower bases of the isosceles trapeziums are connected to a same long side of the rectangle; opposite sides of the two patterns are sides on which multiple isosceles trapeziums are located; equal-length legs and the upper base of the isosceles trapezium are used to grow nanowires; and nanowires grown on upper bases of two isosceles trapeziums, symmetric to each other, on the opposite sides of the two patterns form bridges.
