Atomistic simulation of the structure and elastic properties of pyrite (FeS2) as a function of pressure

Author: Sithole, Happy M ; Ngoepe, PE ; Wright, K Date: Oct 2003 Interatomic potential parameters have been derived at simulated temperatures of 0 K and 300 K to model pyrite FeS2. The predicted pyrite structures are within 1% of those determined experimentally, while the calculated bulk modulus is within ... Read more
Atomistic simulation studies of iron sulphide, platinum antimonide and platinum arsenide

Author: Ngoepe, PE ; Ntoahae, PS ; Mangwejane, SS ; Sithole, Happy M ; Parker, SC ; Wright, KV ; De Leeuw, NH Date: Sep 2005 The authors present the results of atomistic simulations using derived interatomic potentials for the pyrite-structured metal chalcogenides FeS2, PtSb2 and PtAs2. Structural and elastic constants were calculated and compared with experimental ... Read more
