1. Fabrication and characterizationof self-supporting Yttrium foils
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : In this project self-supporting foils with focus on the element yttriumhave been fabricated by means of evaporation and magnetron sputtering.The goal was to see if it was possible to make photochromic selfsupportingyttrium foils. Multiple self-supporting foils were made andsome had suitable properties to be further investigated. READ MORE

2. Correlating Photoconductivity with Photochromism in Oxygen-containing Rare-earth Metal Hydride Thin Films
University essay from Uppsala universitet/MaterialfysikAbstract : Scientists have recently discovered simultaneous photoconductivity and photochromism (i.e., optical switching upon light exposure) of oxygen-containing rare-earth metal hydrides (REMHO). A deep understanding of these extraordinary optical and electrical properties can open the door to advanced technological uses such as smart windows. READ MORE

3. Electric Transport of Rare-earth Metal Oxy-hydride Thin Films
University essay from Uppsala universitet/Materialfysik; Uppsala universitet/Tillämpad kärnfysikAbstract : In this project, I investigate the photoconductivenature of photochromic rare-earth metal oxy hydrides (REMHO). Such materials have received increasingscientific attention since they show a color-neutralphotochromic effect that can be applied, e.g., in smartwindows or chromogenic devices. READ MORE

4. A study of the photochromic effect in oxygen containing rare-earth metal hydride thin films and multilayer structures
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : In this work, we have studied the photochromic response of several oxygen containing rare-earth hydride thin films (REHO, RE = Y, Nd, Gd, and Dy). Their chemical composition was characterized by an iterative multi-method approach based on ion beams, while the photochromic effect was measured by means of optical spectrometry. READ MORE
