Impact of Four-Valent Doping on the Crystallographic Phase Formation for Ferroelectric HfO from First-Principles: Implications for Ferroelectric Memory and Energy-Related Applications
Christopher Künneth, Robin Materlik, Max Falkowski +1
The ferroelectric properties of nanoscale silicon doped HfO promise a multitude of applications ranging from ferroelectric memory to energy-related applications. The reason for…
Symmetry and structure of carbon-nitrogen complexes in gallium arsenide from infrared spectroscopy and first-principles calculations
Christopher Künneth, Simon Kölbl, Hans Edwin Wagner +3
Molecular-like carbon-nitrogen complexes in GaAs are investigated both experimentally and theoretically. Two characteristic high-frequency stretching modes at \num{1973} and \SI{20…
The impact of charge compensated and uncompensated strontium defects on the stabilization of the ferroelectric phase in HfO
Robin Materlik, Christopher Künneth, Thomas Mikolajick +1
Different dopants with their specific dopant concentration can be utilized to produce ferroelectric HfO thin films. In this work it is explored for the example of Sr in a compr…
The Origin of Ferroelectricity in Hf Zr O: A Computational Investigation and a Surface Energy Model
Robin Materlik, Christopher Künneth, Alfred Kersch
The structural, thermal, and dielectric properties of the ferroelectric phase of HfO, ZrO and Hf Zr O (HZO) are investigated with carefully validated de…
