1. 1. Topological properties of flat bands in generalized Kagome lattice materials

   University essay from KTH/Fysik

   Author : Daniela Pinto Dias; [2021]
   Keywords : tight-binding; topological insulators; flat bands; edge states; honeycomb-Kagome lattice; tätt bindande modell; topologiska isolatorer; platta band; kanttillstånder; bikakan-Kagome gitter;

   Abstract : Topological insulators are electronic materials that behave like an ordinary insulator in their bulk but have robust conducting states on their edge. Besides, in some materials the band structure presents completely flat bands, a special feature leading to strong interactions effects. READ MORE

3. 2. Using gallium nitride nanowires as STM probes

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Karolis Sulinskas; [2018]
   Keywords : STM; STS; Nanowire; GaN; InAs; Semiconductors; Physics and Astronomy;

   Abstract : Gallium nitride (GaN) nanowires grown using catalyst-free metal organic vapor phase epitaxy were used as scanning tunneling microscope (STM) probes. The probes were prepared by placing a GaN nanowire on a tungsten STM probe using a nanomanipulator in a scanning electron microscope (SEM) and welding them together using an electron beam induced platinum deposition.
