Signature of the topological surface state in the thermoelectric properties of Bi$_2$Te$_3$

, 2013
We present ab initio electronic structure calculations based on density functional theory for the thermoelectric properties of Bi$_2$Te$_3$ films. Conductivity and thermopower are computed in the diffusive limit of transport based on the Boltzmann ...

Thermoelectric properties of GeSe

Journal of Materiomics, 2016
AbstractThe recently reported superior thermoelectric performance of SnSe, motivates the current work on the thermoelectric properties of polycrystalline GeSe, an analog compound with the same crystal structure. Due to the extremely low carrier concentration in intrinsic GeSe, various dopants are utilized to substitute either Ge or Se for increasing ...

From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers

Advanced Functional Materials, EarlyView.
Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.
