Origin of the Order-Disorder Transition and the Associated Anomalous Change of Thermopower in AgBiS2 Nanocrystals: A Combined Experimental and Theoretical Study

Guin, Satya N.; Banerjee, Swastika; Sanyal, Dirtha; Pati, Swapan Kumar; Biswas, Kanishka (American Chemical Society, 2016)

Bulk AgBiS2 crystallizes in a trigonal crystal structure (space group, P (3) over bar m1) at room temperature, which transforms to a cation disordered rock salt structure (space group, Fm (3) over barm) at similar to 473 ...
Pressure induced structural, electronic topological, and semiconductor to metal transition in AgBiSe2

Rajaji, V.; Malavi, Pallavi S.; Yamijala, Sharma S. R. K. C.; Sorb, Y. A.; Dutta, Utpal; Guin, Satya N.; Joseph, B.; Pati, Swapan Kumar; Karmakar, S.; Biswas, Kanishka; Narayana, Chandrabhas (American Institute Physics, 2016)

We report the effect of strong spin orbit coupling inducing electronic topological and semiconductor to metal transitions on the thermoelectric material AgBiSe2 at high pressures. The synchrotron X-ray diffraction and the ...
