Abstract
A comparison between interface quality of several temperatures thermal annealed HPRS TiO/sub 2/ films and 750 /spl deg/C annealed ALD TiO/sub 2/ films has been established. Our attention has been focused on the interfacial state and disordered induced gap state densities. From our results, HPRS films submitted to in situ 900 /spl deg/C thermal annealing in oxygen atmosphere exhibit the best characteristics, with D/sub it/ density being the lowest value measured in this work (5.6 /spl times/ 10/sup 11/ cm/sup -2/ eV/sup -1/), and undetectable conductance transients within our experimental limits.
