Ultra-duenne Oxid- und Nitridschichten auf den intermetallischen Verbindungen NiAl und CoGa

The formation of oxide and nitride thin films on low indexed surfaces of the intermetallic alloys NiAl and CoGa has been studied. For this purpose, an ultra-high vacuum (UHV) apparatus which facilitates combined in situ investigations by means of scanning tunnelling microscopy (STM), electron energy loss spectroscopy (EELS), low-energy electron diffraction (LEED), Auger electron spectroscopy (AES) and thermal desorption spectroscopy (TDS) was developed. The design of the sample manipulator allows the quasi-simultaneous use of the techniques without changing the sample temperature. In addition, a second apparatus with a combination of the same methods except for STM was used.
