Thermoelectrical detection of Majorana states [PDF]

, 2013
We discuss the thermoelectrical properties of nanowires hosting Majorana edge states. For a Majorana nanowire directly coupled to two normal reservoirs the thermopower always vanishes regardeless of the value of the Majorana hybridization. This situation changes drastically if we insert a quantum dot. Then, the dot Majorana side coupled system exhibits

The Design of Intrinsically Conductive Metal‐Organic Frameworks for Thermoelectric Materials

Small Science, Volume 5, Issue 3, March 2025.
Owing to their high crystallinity combined with high porosity, metal‐organic frameworks (MOFs) appear as a promising class of materials for thermoelectric applications, potentially offering the ideal combination of high electrical and low thermal conductivity.

Cobalt‐Based Materials in Supercapacitors and Batteries: A Review

Advanced Energy and Sustainability Research, Volume 6, Issue 2, February 2025.
Cobalt (Co)‐based materials are appropriate as electrode materials in energy storage devices. A combination of Co and ferrite materials such as nickel, zinc, and copper, or Co with nonferrite materials such as metal–organic frameworks and layered double hydroxides has sparked applied research.

Low-field diffusion magneto-thermopower of a high mobility two-dimensional electron gas [PDF]

, 2004
The low magnetic field diffusion thermopower of a high mobility GaAs-heterostructure has been measured directly on an electrostatically defined micron-scale Hall-bar structure at low temperature (T = 1.6 K) in the low magnetic field regime (B < 1.2 T) where delocalized quantum Hall states do not influence the measurements. The sample design allowed the

Giant Topological Hall Effect and Colossal Magnetoresistance in Heusler Ferromagnet near Room Temperature

Advanced Materials, Volume 37, Issue 3, January 22, 2025.
Ferromagnetic shape memory Heusler alloy Ni2Mn1.4In0.6 exhibits colossal magnetoresistance (CMR) and giant topological Hall effect (THE) near room temperature, which is attributed to the enhanced spin chirality emerging from the formation of domains and domain walls, which in turn resulted from the combined effect of magnetic field induced martensite ...

Giant Power Output from Ionic/electronic Hybrid Nanocomposite Thermoelectric Converter Under Constant Temperature Gradient

Advanced Science, Volume 12, Issue 3, January 20, 2025.
A novel ionic/electronic hybrid nanocomposite TE converter (NCTEC) by integrating carbon nanotube/polylactic acid nanofibrous fabrics (CPNF) with gelatin ionogel is developed. A record‐high output power density is realized by NCTEC with continuous power output at a constant temperature gradient, which is contributed by substantially increased ...

Effect of short-range impurities on low-temperature conductance and thermopower of quantum wires [PDF]

arXiv, 2007
The electron transport through the parabolic quantum wire placed in longitudinal magnetic field in the presence of the system of short-range impurities inside the wire is investigated. Using approach based on the zero-range potential theory we obtained an exact formula for the transmission coefficient of the electron through the wire that allows to ...
