Bias Tunable Transport Modulation and Gas Selectivity in Layered BiOI: A DFT NEGF Study
Jemal Yimer Damte, Jiří Houška, Pavel Baroch +1
Understanding the interplay between adsorption energetics and charge-transport modulation is essential for the rational design of low-power and bias-tunable gas sensors. Here, we p…
Boron-assisted stabilization of low-resistivity mixed-valence Cu-O thin films prepared by reactive magnetron sputtering
Nirmal Kumar, Jemal Yimer Damte, Michal Procházka +5
This study systematically investigated the influence of boron incorporation in Cu-O thin films and the effect of oxygen partial pressure () on the phase evolution, chem…
Ultra-low-resistivity nitrogen-doped p-type Cu2O thin films fabricated by reactive HiPIMS
Jiří Rezek, Jan Koloros, Jiří Houška +5
We have successfully fabricated the nitrogen-doped cuprous oxide thin films on the amorphous standard soda-lime glass by reactive high-power impulse magnetron sputtering. The energ…
First Principles Investigation of Gas Adsorption on Bilayer Transition Metal Dichalcogenides for Sensing Toxic Gases
Jemal Yimer Damte, Hassan Ataalite
Transition metal dichalcogenides have shown great promise in the field of gas sensing due to their high catalytic activity and unique electronic properties. They can effectively in…
Formation of C1 oxygenates by Activation of Methane on B, N Co-doped Graphene Surface Decorated by Oxygen Pre-covered Ir13 Cluster: A First Principles Study
Jemal Yimer Damte, Jiri Houska
We employ density functional theory (DFT) to investigate the adsorption and dehydrogenation of methane on the BNG-Ir13 cluster at both low and high oxygen coverage. The DFT calcula…
Tribo-piezoelectric Nanogenerators for Energy Harvesting: a first-principles study
Jemal Yimer Damte, Jiri Houskaa
Two-dimensional transition metal dichalcogenides (TMDs) are highly promising candidates for various applications due to their unique electrical, optical, mechanical, and chemical p…
