Double crystal x-ray diffractometry is a well established method for the measurement of the lattice parameter difference between expitaxial layers and substrates. The diffracted intensity profile versus angle, rocking curves, are highly sensitive to such variations giving rise t…
The Compact Muon Solenoid (CMS) experiment currently taking data at the Large Hadron Collider (LHC) has the largest ever built all-silicon tracking system with a pixel detector as the innermost component. The pixel detector consists of three 53 cm long barrel layers (BPIX) at ra…
Organic materials are of great interest for use as low cost electronic and optoelectronic devices. However, the performance of organic solar cells is inferior to the performance of inorganic solar cells. There are many factors that affect the quality of the organic solar cells p…
A versatile and sensitive magnetometer has been developed and constructed. The design was based on the concept of a vibrating sample magnetometer originally suggested by S. Foner. A novel pick-up coil arrangement has been installed which minimises noise arising from mechanical v…
The electrical properties of films of metal-polypropylene-metal structures with polypropylene thicknesses in the range 600 - 2600Å were studied for possible use as thin dielectric films and some standard and reproducible results of electrical measurements were obtained. As a con…
