3D TEM characterization of silver implanted silicon for intermediate band solar cells
Lysne, Hogne (Master thesis, 2017)As the need for renewable and sustainable energy sources are growing solar cells are turning into one of the most affordable and widely adopted solutions for renewable electricity production. This is driven by a steady ... -
Electronic structure of thermoelectric and ferro-electric materials: - Advanced transmission electronmicroscopy studies
Sæterli, Ragnhild (Doktoravhandlinger ved NTNU, 1503-8181; 2010:158, Doctoral thesis, 2010)This thesis describes TEM studies related to the electronic structure of thermoelectric and ferroelectric materials. Compounds within the thermoelectric skutterudite class of materials were examined using Electron ... -
On Soot Sampling: Considerations when Sampling for TEM Imaging and Differential Mobility Spectrometer
Emberson, David; Rohani, Behzad; Wang, Liang; Sæterli, Ragnhild; Løvås, Terese (Journal article; Peer reviewed, 2019)Particulate matter (PM) has been sampled from a compression ignition engine using a differential mobility spectrometer (Cambustion DMS 500) and for imaging in a transmission electron microscope (TEM) with the aim of coupling ... -
TEM characterization of Cr-doped ZnS Thin Films for Solar Cell applications
Seim, Eivind (Master thesis, 2014)The morphology of three Cr-doped zinc sulfide thin films, one deposited by molec-ular beam epitaxy (MBE) and two by pulsed laser deposition (PLD), have beenstudied by transmission electron microscopy (TEM). Investigations ... -
Transmission Electron Microscopy Characterisation of Lead-Free KNN Thin Films
Toresen, Andreas (Master thesis, 2018)Lead-free piezoelectric ceramics have in recent years received an increased interest. Potassium sodium niobate (KNN) has shown promising results, exhibiting properties close to todays dominating piezoelectric material lead ... -
Transmission electron microscopy characterization of quantum dot based intermediate band solar cells
Undheim, Espen (Master thesis, 2014)In this thesis, two samples of quantum dot based intermediate band solar cells were studied and compared by transmission electron microscopy. These samples were grown on a (100) GaAs substrate, with a general structure ...
