2. 1. Initial stages of metal- and organic-semiconductor interface formation

   Author : Pål Palmgren; Mats Göthelid; Mikael Grehk; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiconductor physics; Halvledarfysik;

   Abstract : This licentiate thesis deals with the electronic and geometrical properties of metal-semiconductor and organic-semiconductor interfaces investigated by photoelectron spectroscopy and scanning tunneling microscopy. First in line is the Co-InAs interface (metal-semiconductor) where it is found that Co is reactive and upon adsorption and thermal treatment it alloys with the indium of the substrate to form metallic islands, about 20 nm in diameter.

4. 2. Phthalocyanine interfaces : the monolayer region

   Author : Pål Palmgren; Mats Göthelid; Mats Fahlman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phthalocyanine; III-V semiconductor; transition metal oxides; adsorption; self-assembly; Material physics with surface physics; Materialfysik med ytfysik;

   Abstract : Organic molecules adsorbed on inorganic substrates are the topics of interest in this thesis. Interfaces of this kind are found in dye sensitized solar cells that convert solar energy to electricity, a promising environmentally friendly energy source which might provide a route to replace fossil fuels.
