The Fundamental Absorption Edge Tail of Ferroelectric SbSI
The temperature dependence of the fundamental absorption edge of SbSI is studied in the range 320 to 5 K. In the paraelectric phase the edge is described by the Urbach's rule. The pertinent parameters of the ferroelectric phase are found to be temperature dependent. The influence of spontaneous...

description | The temperature dependence of the fundamental absorption edge of SbSI is studied in the range 320 to 5 K. In the paraelectric phase the edge is described by the Urbach's rule. The pertinent parameters of the ferroelectric phase are found to be temperature dependent. The influence of spontaneous polarisation on the absorption edge is discussed. The unusual Urbach behaviour in the ferroelectric phase is explained by the temperature dependence of the spontaneous polarisation. The results of SbSI absorption edge studies are found to be consistent with the microscopic model of Sumi‐Toyozawa.
Es wird die Temperaturabhängigkeit der fundamentalen Absorptionskante von SbSJ‐Einkristallen im Temperaturbereich 320 bis 5 K untersucht. In der paraelektrischen Phase wird die Absorptions‐kante durch die Urbach‐Regel beschrieben. In der ferroelektrischen Phase hängen die Urbach‐parameter von der Temperatur ab. Die merkwürdige Temperaturabhängigkeit der Urbach‐Absorptionskante in der ferroelektrischen Phase wird durch die Temperaturabhängigkeit der Spontan‐polarisation hervorgerufen. Es wird festgestellt, daß die Meßergebnisse der Absorptionskante von SbSJ gut mit dem mikroskopischen Modell Sumi‐Toyozawa übereinstimmen. |
