Compression mechanisms in quasimolecular XI(3) (X = As, Sb, Bi) solids (1998)
Journal Article
Hsueh, H., Chen, R., Vass, H., Clark, S., Ackland, G., Poon, W., & Crain, J. (1998). Compression mechanisms in quasimolecular XI(3) (X = As, Sb, Bi) solids. Physical review B, 58(22), 14812-14822. https://doi.org/10.1103/physrevb.58.14812

We explore the structural, vibrational, and electronic properties of a prototypical family of quasimolecular layered solid of the type XI3 where (X=As,Sb,Bi) under compression. We use a combination of angle- dispersive powder x-ray diffraction and Ra... Read More about Compression mechanisms in quasimolecular XI(3) (X = As, Sb, Bi) solids.

Structure and electronic properties of FeSi2 (1998)
Journal Article
Clark, S., Al-Allak, H., Brand, S., & Abram, R. (1998). Structure and electronic properties of FeSi2. Physical review B, 58(16), 10389-10393. https://doi.org/10.1103/physrevb.58.10389

The nature of the band gap in the semiconducting material beta-FeSi2 is still under some dispute. Although most experimental results indicate the band gap to be direct, nb initio work generally reports the material to be an indirect semiconductor wit...
