X-ray absorption and reflection as probes of the GaN conduction bands: Theory and experiments
- Case Western Reserve Univ., Cleveland, OH (United States); and others
X-ray absorption measurements are a well-known probe of the unoccupied states in a material. The same information can be obtained by using glancing angle X-ray reflectivity. In spite of several existing band structure calculations of the group III nitrides and previous optical studies in UV range, a direct probe of their conduction band densities of states is of interest. The authors performed a joint experimental and theoretical investigation using both of these experimental techniques for wurtzite GaN.
