We investigated unusual low temperature transport properties of InSb single crystals doped with manganese to concentrations in the range of 1017<NMn<2*1017cm-3 which includes the critical concentration for metal-insulator transition Ncr= 2*1017cm-3. It was found that in the temperature range T=10÷1.5K the resisitivity had an unusual behavior described by an exponential quadratic function ρ ∼ exp(Δ1/kT)2 where Δ1 varied from Δ1=0.3meV to Δ1=0. Coexistence of electrons and holes at temperatures around the metal-insulator transition in p-InSb(Mn) crystals gives the ground to explain the unusual temperature - resistivity dependence in the framework of excitonic insulator phase model (L. V. Keldysh and Yu. V. Kopaev, Sov. Phys. Solid State 6, 2219 (1965))

“…Consequently, these compounds have found use in a range of semiconductor applications, such as non-linear optical devices 2,3 , photodiodes 4,5 , spintronic devices 6,7 , and more recently, thin film intermediate band solar cells 8 . Copper-iron-sulfide chalcopyrite (CuFeS 2 ) is also commercially the most important copper ore as it accounts for the majority of copper reserves.…”

The geometric, electronic and magnetic properties of bulk chalcopyrite CuFeS 2 have been investigated using hybrid-exchange density functional theory calculations. The results are compared with available theoretical and experimental data. The theoretical description of the bonding and electronic structure in CuFeS 2 is analyzed in detail and compared to those computed for chalcocite (CuS 2 ) and greigite (Fe 3 S 4 ).In particular, the behavior of the 3d electrons of Fe 3+ are discussed in terms of the Hubbard-Anderson model in the strongly correlated regime and found to be similarly described in both materials by an on-site Coulomb repulsion (U ) of ∼8.9 eV and a transfer integral (t) of ∼0.3 eV. a) vincent.chen08@imperial.ac.uk
