This proposal aims at establishing microstructural indicators for the performance of thin film devices. Microstructural studies and analytical investigations of the local chemistry will be carried out by transmission and scanning transmission electron microscopies (TEM and STEM) and the findings will be correlated to optical and electrical measurements. More specifically the scientific aims are:(i) to gain an understanding of the microstructural defects, which determine the degradation processes in high power GaAs and InP based lasers,(ii) to find microstructural and micro-chemical indicators for the efficiency of CdTe/CdS solar cells and (iii) to determine the microstructural and micro-chemical properties which govern the electrical characteristics of monolithically integrated poly-silicon transistors in large array active matrix liquid crystal displays.The program relies crucially on the fabrication of electron microscopy specimens in particular for inspection in the STEM. Electron microscopy of individual devices requires the attainment of electron transparent area with mm local precision. Such specimens can only be made by means of precision ion beam milling techniques. Whilst the proposed programs are all already funded, they are currently hampered by the lack of precision ion beam milling capacity. The only machine available is owned by the Materials Science Department at Manchester University and is primarily committed to other programs. The Condensed Matter Physics group of the Physics Department at UMIST, due to its expertise in TEM and STEM of semiconducting materials and in particular actual devices, has recently become involved in a large number of microstructural projects and it is of foremost importance for the group to possess its own precision milling machine.
