Sometimes two photons are better than one. A new two-photon-absorption technique developed at the US Naval Research Laboratory in Washington for testing the radiation sensitivity of semiconductors could lead to more robust integrated circuits for space- based applications and for advanced earthbound devices. A new two-photon absorption technique enables users to investigate the effects of radiation on electronic devices by controllably inducing errors into a circuit. An electron-hole density plot as a function of depth for 1-nJ, 120-fs pulses of 1.26-µm radiation in silicon illustrates...Read full article
