From: Efficient and surface site-selective ion desorption by positron annihilation
TOF spectra of ions desorbed from a TiO2(110) surface by (a) positron and (b) electron bombardment at an incident energy of 500 eV. Each spectrum was normalised to the number of incident particles. The blue dashed line in (b) indicates ESD results enlarged by a factor of 25.
