Impact of hydrogen incorporation on electronic and magnetic structure of X2CrNi18-9 stainless steel
Torben Tappe, Louis Becker, Gaurav Kanu +7
Hydrogen absorption significantly alters the mechanical properties of steel. However, absorbed hydrogen also influences its electronic and magneto-structural properties, helping to…
Influence of Charge Density Waves on the Hall coefficient in NiTi
Adrian Braun, Henrik Dick, Timon Sieweke +4
We present a mean-field charge density wave theory for NiTi using density functional theory bandstructure as a starting point. We calculate the Hall coefficient as a function of te…
NiTi Single Crystal Growth by Micro-Pulling-Down Method: Experimental Setup and Material Characterization
Timon Sieweke, Chris Luther, Martin Wortmann +14
Nickel-titanium that has an austenite to martensite phase transition has been studied extensively in the past as a shape memory alloy, but a lot remains to be learned from such pha…
The thermoelectric conversion efficiency problem: Insights from the electron gas thermodynamics close to a phase transition
I. Khomchenko, A. Ryzhov, F. Maculewicz +10
The bottleneck in modern thermoelectric power generation and cooling is the low energy conversion efficiency of thermoelectric materials. The detrimental effects of lattice phonons…
