Defect Characteristics in Different Crystallographic Directions in CzSi as a Function of Doping and Annealing

Abstract

Measurements of the S‐parameter as well as of lifetimes are performed as a function of thermal annealing in the 20 to 1100 °C range. CzSi with different levels of boron doping is investigated. A significant broadening of the annihilation line is found around 800 °C for the heavily doped sample. Concurrent with this a short‐lived (≈ 100 ps) lifetime component is observed with an intensity up to 30%. No obvious changes in the anisotropy of the annihilation line take place. Lebensdauer‐ und S‐Parametermessungen werden in CzSi mit unterschiedlichem Borgehalt als Funktion Von isochroner thermischer Behandlung durchgeführt. Eine signifikante Verbreiterung der Annihilationslinie zusammen mit dem Auftreten einer kurzlebigen Lebensdauerkomponente kann im Bereich um 800 °C festgestellt werden.
