Abstract

Experimental results are reported on the I-III-V Zintl compounds RbGaSb, K₃Ga₃As₄, and K₄In₄As₆ with respect to laser ablation and subsequent laser ionization/removal processes. The approach takes advantage of the low ionization potentials of the group I elements to achieve selectivity and exert a measure of control over neutral mixtures. A 308 nm laser pulse is used to ablate a I-III-V Zintl compound, while a second laser is used to selectively ionize the ejected species within the extraction region of a time-of-flight mass spectrometer. With the second laser operating at 248 nm (in the case of RbGaSb) and at 266 nm (in the case of K₃Ga₃As₄ and K₄In₄As₆), selective gas-phase ionization and removal of the group I elements is clearly demonstrated. © 1998 American Institute of Physics.
