Non-stoichiometric amorphous magnesium-iron silicates in circumstellar dust shells. Dust growth in outflows from supergiants
Hans-Peter Gail, Akemi Tamanai, Annemarie Pucci +1
We investigate the dust growth in oxygen-rich stellar outflows for a set of nine well-observed massive supergiants with optically thin dust shells. Models of the infrared emission…
Plasmon Standing Waves by Oxidation of Si(553)-Au
Z. Mamiyev, M. Tzschoppe, C. Huck +2
Self-assembled Au atomic wires on stepped Si surfaces are metallic, as evidenced by a one-dimensionally dispersing plasmonic excitation. Here we investigate the effects of oxidizat…
Optical properties of non-stoichiometric amorphous silicates with application to circumstellar dust extinction
Akemi Tamanai, Annemarie Pucci, Ralf Dohmen +1
Optical constants of non-stoichiometric amorphous magnesium-iron silicates are determined. It is demonstrated that these can well reproduce the observed mid-infrared emission spect…
Optical Phonons in Methylammonium Lead Halide Perovskites and Implications for Charge Transport
Michael Sendner, Pabitra K. Nayak, David A. Egger +8
Lead-halide perovskites are promising materials for opto-electronic applications. Recent reports indicated that their mechanical and electronic properties are strongly affected by…
Silicate condensation in Mira variables
Hans-Peter Gail, Michael Scholz, Annemarie Pucci
We study whether the condensation of silicate dust in Mira envelopes could be caused by cluster formation by the abundant SiO molecules. For a simplified model of the pulsational m…
Seed particle formation for silicate dust condensation by SiO nucleation
H. -P. Gail, S. Wetzel, A. Pucci +1
Clustering of the abundant SiO molecules has been discussed as a possible mechanism of seed particle formation for silicate dust in stellar outflows with an oxygen rich element mix…
