Flame spray pyrolysis (FSP) allowed quenching the high temperature phase In4Sn3O12 in the form of highly single crystalline particles of about 6 nm. These nanoparticles were in situ deposited to form stable porous films on interdigitated electrodes.

Two SnO2 materials synthesized from SnCl4 and Sn(CH3COO)2 precursors were investigated concerning their hydrogen sensing properties in different oxygen backgrounds. At very low oxygen concentrations one observes a huge increase in the sensor response

In4Sn3O12 is considered as a high temperature phase of the binary In2O3 SnO2 mixture. As shown by Isomaki et al, this specific phase is stable in the temperature region of about 1.600 °C to, depending on the mole fraction, 1.950 °C. Furthermore, th

We measured secondary-electron energy spectra of the H-like ions N[sup 6+], O[sup 7+], and Ne[sup [ital q]+]([ital q]=3,7,8,9,10) incident on a solid Pt(110) surface at different angles (10[degree]--90[degree]) using impact energies of 10[ital q] and

The interaction of highly charged ions on clean metal surfaces causes the emission of secondary electrons both from the projectile and the target. Angular and energy resolved spectroscopy of the electrons being emitted from the projectile provides in
