Tuning thermoelectric properties of Sb $_{2}$ Te $_{3}$ -AgSbTe $_{2}$ nanocomposite thin film -- synergy of band engineering and heat transport modulation

Abhishek Ghosh, Khushboo Agarwal, Sergio Gonzalez Munoz +9

The present study demonstrates a large enhancement in the Seebeck coefficient and ultralow thermal conductivity (TE) in Sb $_{2}$ Te $_{3}$ -AgSbTe $_{2}$ nanocomposite thin film. The additio…

Controlling local resistance via electric-field induced dislocations

D. M. Evans, D. R. Småbråten, T. S. Holstad +7

Dislocations are one-dimensional (1D) topological line defects where the lattice deviates from the perfect crystal structure. The presence of dislocations transcends condensed matt…

Assessing electron beam sensitivity for SrTiO $_{3}$ and La $_{0.7}$ Sr $_{0.3}$ MnO $_{3}$ using electron energy loss spectroscopy

Magnus Nord, Per Erik Vullum, Ingrid Hallsteinsen +2

Thresholds for beam damage have been assessed for La $_{0.7}$ Sr $_{0.3}$ MnO $_{3}$ and SrTiO $_{3}$ as a function of electron probe current and exposure time at 80 and 200 kV acceleration…
