Deconvolution of time-gated cathodoluminescence images

摘要

A method for generating a cathodoluminescence map comprising the steps of: generating an intensity modulated charged particle beam; focusing said charged particle beam on a specimen; gating temporally the cathodoluminescence emitted by said specimen to provide time-gated cathodoluminescence; measuring the time-gated cathodoluminescence for different charged particle beam positions on the specimen to generate a cathodoluminescence map; deconvoluting the cathodoluminescence map to improve the resolution of said cathodoluminescence map. The invention further provides devices for carrying out such methods.
