Fabrication of Nanostructures Using Atomic Force Microscopy
Doupal, Antonín ; Škoda, David (referee) ; Bartošík, Miroslav (advisor)
This bachelor thesis deals with fabrication of nanostructures using atomic force microscopy. The theoretical part gives a brief introduction into atomic force microscopy and local anodic oxidation and it is based on literature retrieval. The experimental part is concentrated on investigation of influence of operational parameters (tip-sample voltage, speed of the tip) on dimensions of LAO nanostructures on Si(111). Further the selective growth of cobalt and gallium on such oxide nanostructures is observed and analysed.

Study of Properties of Metallic Thin Films and Nanostructures Using Scanning Probe Microscopy
Doupal, Antonín ; Fejfar, Antonín (referee) ; Kalousek, Radek (advisor)
This diploma thesis is focused on investigation of metallic thin films and nanostructures using scanning probe microscopy. Magnetic properties of these objects are studied by magnetic force microscopy, which is modification of scanning probe microscopy. In the theoretical part basic principles of scanning probe microscopy and magnetic force microscopy are summarized, and also principle of creation of magnetic domains and some special properties of ferromagnetic and antiferromagnetic materials. Further, two techniques of fabricating nanostructures are described. Experimental part is focused on imaging and simulating of magnetic domains. Further, exchange bias is revealed. This phenomenon is present in systems composed from ferromagnetic and antiferromagnetic materials. One part of this diploma thesis is also focused on discussion of problems with magnetic force microscopy.
