Evidence for an ultrafast breakdown of the BeO band structure due to swift argon and xenon ions
Schiwietz, Gregor; Czerski, Konrad; Roth, Melanie; Grande, Pedro Luis; Koteski, V.; Staufenbiel, Friedrich (2010) [Artigo de periódico]Auger-electron spectra associated with Be atoms in the pure metal lattice and in the stoichiometric oxide have been investigated for different incident charged particles. For fast incident electrons, for Ar⁷⁺ and Ar¹⁵⁺ ... -
Indications for enhanced Auger-electron absorption in a hot-electron gas
Schiwietz, Gregor; Roth, Melanie; Czerski, Konrad; Staufenbiel, Friedrich; Grande, Pedro Luis (2007) [Artigo de periódico]Solid-state Auger-electron angular distributions are known to be largely independent of the type of excitation, following roughly a cosine law for low ejection energies. In this Letter it is shown that the iontrack dynamics ... -
Interplay between the Coulomb explosion and vicinage effects studied using H/sub 2//sup +/ molecules under channeling conditions
Fadanelli Filho, Raul Carlos; Grande, Pedro Luis; Behar, Moni; Dias, Johnny Ferraz; Czerski, Konrad; Schiwietz, Gregor (2006) [Artigo de periódico]The aim of this work is to investigate how the mean energy loss and straggling due to H2 + molecules interacting with silicon are affected by the Coulomb explosion and vicinage effects. To that end, a SIMOX-type sample ...
