(2009-05-15)This dissertation focuses on three separate studies. First, magnetization of the Mn12- acetate was studied by low temperature hysteresis loops and DC magnetization data on magnetically aligned Mn12-acetate micro-crystals. ...
-
(2012-07-16)Organic molecules such as porphyrins and alkanethiols are currently being investigated for applications such as sensors, light-emitting diodes and single electron transistors. Porphyrins are stable, highly conjugated ...

(2010-10-12)A low temperature scanning tunneling microscope (LTSTM) was built that we could use in an ultra high vacuum (UHV) system. The scanning tunneling microscope (STM) was tested on an existing 3He cryostat and calibrated at ...

(2014-12-17)I report my studies of Mn12O12(C6H5COO)16(H2O)4, which will be referred to as Mn12-Ph, a single molecule magnet, on Cu(111) and HOPG (highly oriented pyrolytic graphite) surfaces by scanning tunneling microscopy (STM). A ...

Scanning Tunneling Microscopy Studies of Metal Clusters Supported on Graphene and Silica Thin Film (2012-10-19)The understanding of nucleation and growth of metals on a planar support at the atomic level is critical for both surface science research and heterogeneous catalysis studies. In this dissertation, two planar substrates, ...

(2009-05-15)An atomic level understanding of the structure and stability of model catalysts is essential for surface science studies in heterogeneous catalysis. Scanning tunneling microscopy (STM) can operate both in UHV and under ...

(2015-08-07)We employ cross–sectional scanning tunneling microscopy to obtain an accurate statistical representation of the as–grown heterojunctions delineating the quantum wells and quantum barriers in InAlAs / InGaAs strain–balanced ...
