Studies on the Al2O3–Ti–Mo–Au metallization system

The behavior of Ti–Mo–Au metallization on Al2O3 and C has been investigated by backscattering spectrometry. Results show that Mo–Au bimetal films typically mix during deposition. Diffusion of Ti in Mo film occurs at 600°C, but is inhibited by the presence of oxygen in the Ti film. Even 1000 Å of Mo is not a barrier against interdiffusion of Ti and Au during 20–min anneals at 600°C. The amount of mixing observed also depends on the nature of the substrate which supports the Ti–Mo–Au metallization

Altruistic versus profit maximising system operators of rural power systems

This paper presents a methodology using Monte Carlo Simulation for analysing and compare the impact of two types of monopolistic rural power system operators (altruistic and profit maximising operators) on the probability distribution of tariff levels and reliability of the system. The market has price sensitive consumers. The developed model has been demonstrated on two power systems: only diesel genset and a wind-diesel hybrid system showing the impact of the generation costs and capacity of generation from wind on the tariff levels, expected profit and reliability.© 2007 IEEE.
