Local doping of an oxide semiconductor by voltage-driven splitting of anti-Frenkel defects
Jiali He, Ursula Ludacka, Kasper A. Hunnestad +12
Layered oxides exhibit high ionic mobility and chemical flexibility, attracting interest as cathode materials for lithium-ion batteries and the pairing of hydrogen production and c…
Tuning thermoelectric properties of SbTe-AgSbTe 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 SbTe-AgSbTe nanocomposite thin film. The additio…
Atomic-scale 3D imaging of individual dopant atoms in a complex oxide
K. A. Hunnestad, C. Hatzoglou, Z. M. Khalid +6
A small percentage of dopant atoms can completely change the physical properties of the host material. For example, chemical doping controls the electronic transport behavior of se…
Quantitative strain analysis of InAs/GaAs quantum dot materials
Per Erik Vullum, Magnus Nord, Maryam Vatanparast +5
Geometric phase analysis has been applied to high resolution aberration corrected (scanning) transmission electron microscopy images of InAs/GaAs quantum dot (QD) materials. We sho…
Bandgap measurement of high refractive index materials by off-axis EELS
Maryam Vatanparast, Ricardo Egoavil, Turid W. Reenaas +3
In the present work, Cs aberration corrected and monochromated scanning transmission electron microscopy electron energy loss spectroscopy STEM-EELS has been used to explore experi…
Assessing electron beam sensitivity for SrTiO and LaSrMnO using electron energy loss spectroscopy
Magnus Nord, Per Erik Vullum, Ingrid Hallsteinsen +2
Thresholds for beam damage have been assessed for LaSrMnO and SrTiO as a function of electron probe current and exposure time at 80 and 200 kV acceleration…
