The Excess Wing in the Dielectric Loss of Glass-Formers: A Johari-Goldstein beta-Relaxation?
U. Schneider, R. Brand, P. Lunkenheimer +1
Dielectric loss spectra of glass-forming propylene carbonate and glycerol at temperatures above and below T_g are presented. By performing aging experiments lasting up to five week…
The excess wing in the dielectric loss of glass-forming ethanol: A relaxation process
R. Brand, P. Lunkenheimer, U. Schneider +1
A detailed dielectric investigation of liquid, supercooled liquid, and glassy ethanol reveals a third relaxation process, in addition to the two processes already known. The relaxa…
Wide range dielectric spectroscopy on glass-forming materials: an experimental overview
U. Schneider, P. Lunkenheimer, A. Pimenov +2
Dielectric spectroscopy is one of the most commonly used techniques for the investigation of the dynamic response of glass-forming materials. The tremendous slow-down of the partic…
Fast Dynamics of Glass-forming Liquids investigated by Dielectric Spectroscopy: a Comparison
U. Schneider, P. Lunkenheimer, R. Brand +1
We have performed dielectric spectroscopy on the molecular glass-formers glycerol, propylene carbonate (PC) and the ionic melts CKN and CRN. The frequency range covers almost 20 de…
Scaling of broadband dielectric data of glass-forming liquids and plastic crystals
U. Schneider, R. Brand, P. Lunkenheimer +1
The Nagel-scaling and the modified scaling procedure proposed recently by Dendzik et al. have been applied to broadband dielectric data on two glass- forming liquids (glycerol and…
Broadband dielectric response of glycerol and propylene carbonate: a comparison
P. Lunkenheimer, U. Schneider, R. Brand +1
Dielectric data on glycerol and propylene carbonate covering 18 decades of frequency are presented and compared to each other. Both materials exhibit qualitatively similar behavior…
Broadband Dielectric Spectroscopy on Glass-Forming Propylene Carbonate
U. Schneider, P. Lunkenheimer, R. Brand +1
Dielectric spectroscopy covering more than 18 decades of frequency has been performed on propylene carbonate in its liquid and supercooled-liquid state. Using quasi-optic submillim…
