21. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C
Sammanfattning : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. LÄS MER
22. Resistive studies of vortices and fluctuations in single crystal YBa2Cu3O7-
Sammanfattning : High-temperature superconductors have been intensely studiedsince the discovery, almost 20 years ago. Their layeredstructure, extreme type-II behavior, large anisotropy, andstrong fluctuations have led to a large number of new andinteresting problems. LÄS MER
23. Dynamics of metal oxides surfaces and the connection to reactivity
Sammanfattning : Many interesting chemical and physical phenomena which take place on surfaces of metaloxides rely on the material's ability to repeatedly alter the electronic surface structure. Formost metal oxides this functionality is connected to the degree of non-stoichiometry andthe presence of structural defects. LÄS MER
24. Symmetric scanning tunneling microscopes for ultra high vacuum and very low temperatures
Sammanfattning : .... LÄS MER
25. Solving Mysteries and Outwitting Transitions : Investigating the Incommensurate Crystal Structures of AuIn and Sn3Sb2
Sammanfattning : This thesis introduces two new incommensurate alloys. AuIn shows variable amounts of modulation, depending on the measurement temperature. At 400°C the diffraction pattern shows diffuse scattering and a thallium iodide type Cmcm space group. LÄS MER
