1. Deep levels in SiC
Sammanfattning : Silicon carbide (SiC) has been discussed as a promising material for high power bipolar devices for almost twenty years. Advances in SiC crystal growth especially the development of chemical vapor deposition (CVD) have enabled the fabrication of high quality material. LÄS MER
2. Anomalous Spectral Lines in Space and Laboratory Plasmas - Studies with HST and CRYRING
Sammanfattning : Eta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. LÄS MER
3. Lifetime measurements of metastable levels in positive and negative singly charged ions
Sammanfattning : .... LÄS MER
4. Weak Atomic Interactions
Sammanfattning : An atom or ion can change quantum state, usually through emission or absorption of a photon. The photon has the same energy as the energy difference between the states of the transition. The states, or energy levels, of an atom are quantized and light emitted, or absorbed, from the atom is therefore of specific wavelengths, giving spectral lines. LÄS MER
5. Deformation induced martensitic transformation of metastable stainless steel AISI 301
Sammanfattning : Metastable stainless steels are promising engineering materials demonstrating good corrosion resistance and mechanical properties. Their mechanical properties are however significantly affected by the deformation induced martensitic transformation. LÄS MER
