Parisini, A. ; Tarricone, L. ; Bellani, V. ; Parravicini, G. B. ; Díaz García, Elena ; Domínguez-Adame Acosta, Francisco ; Hey, R. | American Physical Society | 2001-01-15

We report a systematic study of several GaAs-AlxGa1-xAs semiconductor superlattices grown by molecular-beam epitaxy specifically designed to explore the existence of extended states in random dimer superlattices. We have confirmed our previous r[...]

Ellipsometric characterization of random and random-dimer GaAs-Alx-Ga_(1-x)As superlattices

Bellani, V. ; Parravicini, G. B. ; Díez, E. ; Domínguez-Adame Acosta, Francisco ; Hey, R. | American Physical Society | 2002-11-15

We studied the optical properties of ordered and intentionally disordered GaAs-AlxGa1-xAs superlattices, with and without dimer-type correlations in the disorder, by means of spectroscopic ellipsometry. The electronic structure of the superlatti[...]
