1. Charge Density Waves and Alkali Metal Intercalation in Layered Materials
Abstract : In this thesis the following issues are discussed: 1. Fundamental properties of two polytypes of TaS2 studied by scanning tunneling microscopy (STM) and spectroscopy (STS). 2. The influence of Na intercalation on charge density waves (CDW's) in 1T-VSe2 and 4Hb-TaS2 studied by STM and STS. READ MORE

2. Atomically Resolved ac-Mode Atomic Force Microscopy in Ultra-High Vacuum
Abstract : When the atomic force microscope (AFM) was invented in 1986, it was anticipated that the technique should be able to produce atomically resolved images with aquality similar to what was routinely obtained with the scanning tunnelling microscope (STM). Even though the AFM quickly became a very popular technique, the development toward ultra-high resolution imaging turned out to be slow due to problems of both fundamental and technical nature.
