Autor: Balogh-Michels Zoltán, Stevanovic Igor, Frison Ruggero, Bächli Andreas, Schachtler Daniel, Gischkat Thomas, Neels Antonia, Stuck Alexander, Botha Roelene

Publikováno v: EPJ Web of Conferences, Vol 238, p 12004 (2020)

We present our investigation on the crystallization of IBS HfO2 on (0001) SiO2. The crystallization was studied by in-situ XRD. The activation energy was 2.6±0.5 eV. The growth follows a two-dimensional mode. LIDT measurements (5000-on-1) with 10 ns
