Group founder Prof. Dr. Roland Weingärtner

ROLAND WEINGÄRTNE

Dr. Roland Weingärtner founded the Materials Science Group of the Physics Section at the Pontificia Universidad Católica del Perú (PUCP) in 2005 in the frame work of a research project funded for 5 years by the Deutsche Forschungsgemeinschaft (DFG) in collaboration with the Friedrich Alexander Universität (FAU). The DFG project in 2005 included the setup of a new laboratory, installing a RF-sputtering deposition system. This enabled the deposition and study of the light emission properties of amorphous wide-bandgap semiconductors SiC, SiN and AlN doped with rare earths (RE). During his leadership, the group has expanded its activities covering wider research topics which have been supported by different projects in recent years. In 2018, after 13 years of pioneering work in Peru, Dr. Weingärtner returned to Germany to continue his career. For both his professional and private future, the Materials Science Group wishes Dr. Weingärtner all the best and continued success.

Dr. Ing. Oliver Erlenbach

OLIVER ERLENBACH

In 2005, Oliver Erlenbach student at the Friedrich-Alexander University Erlangen-Nuremberg came to the PUCP in order to perform his PhD in materials science, financed by the DAAD. This PhD has been carried out within the framework of cooperation with the PUCP and University of Erlangen. A major part of the scientific research for this PhD took place in Lima, Peru, where Oliver Erlenbach participated in establishing a new material research laboratory for the production of thin films using RF magnetron sputtering deposition in the framework of a DFG/BMZ project. In his PhD thesis, he focused on the optical characterization of lanthanide doped (SiC)1-x(AlN)x-films in particular.

MSc. Johan Llamoza

The spectra generated from thin films in the order of nanometers (200-500 nm) produce additional spectrum fringes that impede the analysis of samples, furthermore it produces fictitious transmittance greater than 100%. This work aims to mathematically describe these fringes, to implement the Hodrick-Prescott algorithm, which estimates the cyclical part of a data sequence, baseline data in our case. With the specter corrected estimate the number bonds of the sample, and percentage of crystallinity. Finally study the degradation of the samples.
