Electron spectrum and quantum capacity of intercalated packet-ordered layered semiconducting structures

I.V. Stasyuk
O.V. Velychko

Influence of intercalation on the electronic band structure of the layered nanohybrid compound of the GaSe-type with a stage ordering, formed by packets with the small number of layers, is studied within the modified version of the periodic Anderson model. Density of electron states (electron DOS) and electron contribution into quantum capacity of the system are calculated and analyzed for the case of neutral impurities with the local level broadening (of the Lorentzian-type) due to electron correlations. The anomalous behaviour of the electron components of capacity in the region of the DOS singularities (appearing due to stage ordering and hybridization effects) is revealed and studied. Changes in the total DOS and the quantum capacity because of impurity level broadening ($\Gamma$) and increase of the intercalant concentration ($x$) are investigated.
