1. 11. Nanostructural design of transition metal nitride thin films

   Författare :Torbjörn Joelsson; Ivan Petrov; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : Early transition metal nitrides have found extensive use in a range of thin film applications. We are just beginning to understand their growth from vapor phase deposition and microstructure-property relationships. LÄS MER

3. 12. Electronic Structure Calculations: Materials with Weak and Strong Correlations

   Författare :Krister Karlsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoemission spectroscopy; band structure calculations;

   Sammanfattning : This thesis is devoted to studies of various electronic properties which can be extracted from photoemission spectroscopy. Both weakly and strongly correlated systems are discussed, ranging from free electron metal surfaces to strongly correlated copper oxide compounds. LÄS MER

4. 13. Magnetism of manganites, semiconductors and spin glasses

   Författare :Roland Mathieu; Ian Campbell; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; fasta tillståndets fysik; Solid State Physics;

   Sammanfattning : Magnetic and electrical properties of selected compounds containing manganese (Mn) are investigated by SQUID magnetometry and transport measurements.(Ga,Mn)As is a magnetic semiconductor obtained from GaAs by substituting Ga3+ for Mn2+. Mn acts in the alloy as a magnetic impurity, as well as a hole dopant. LÄS MER
