The Center for Materials Research

Welcome to the web sites of the Center for Materials Research: Welcome to the web sites of the Center for Materials Research!

The Center for Materials Research is an interdisciplinary university research center at JLU.
It is dedicated to the implementation of joint research projects, the support of the study courses in materials science and it promotes scientific qualification in materials research.

An overview of our scientific team is available under
Team & Topics.

The center provides the participating research groups with central experimental resources in its
Method Platforms.

The ZfM coordinates the JLU research profile area ("area of potential")
Material and Energy (focus: storage materials).

Less defects for better electronics: cubic nitrides put to the test

Cubic nitrides are of considerable interest for modern electronic and optoelectronic devices. Impedance spectroscopy, together with C–V and frequency-dependent conductance measurements, enables the investigation of transport processes and electrically active defects at the interfaces of cubic GaN/AlN heterostructures. Our impedance spectra reveal low-frequency processes attributed to charge accumulation and space-charge effects at the AlN/GaN and AlN/SiC interfaces. Interface characterization using Mott–Schottky analysis reveals a reduction in the impurity concentration, while the conductance method indicates a decrease in the interface trap density. Notably, the latter is two orders of magnitude lower than typical values reported for hexagonal GaN heterostructures. The decreasing defect densities suggest an improvement in crystalline quality with increasing GaN layer thickness.
