Publication highlights

  1. Experimental evidence of new tetragonal polymorphs of silicon formed through ultrafast laser induced confined micro explosion
 
    L. Rapp, B. Haberl, C.J. Pickard, J.E. Bradby, E.G. Gamaly, J.S.Williams, S. Juodkazis, A.V. Rode

    Nature Communication 6:7555 (2015) 

    A study demonstrating the formation of two novel metastable Si phases by the ultrafast laser induced confined microexplosion method, predicted theoretically but never observed in nature or in laboratory experiments. Theoretical prediction of four more new Si-allotropes with 32 atoms in a primitive cell, two tetragonal and two monoclinical.

    “The real breakthrough has happened in 2015 when Rapp et al. have found evidence for several metastable silicon phases after ultrashort laser-induced confined microexplosions[..]. They have determined the lattice parameters and possible atomic structures of [...] phases: [...] The exotic silicon phases and those new discovered by Rapp et al. have provided a novel insight into the local structure and properties of the amorphous phase of silicon.” Dmitrienko et al., Phys.
