Growth Pattern of Silicon Clusters
Atul Bahel, Jun Pan, Mushti V. Ramakrishna
Tight-binding molecular dynamics simulated annealing technique is employed to search for the ground state geometries of silicon clusters containing 11-17 atoms. These studies revea…
Chemistry of Nanoscale Semiconductor Clusters
Jun Pan, Atul Bahel, Mushti V. Ramakrishna
The ground state structures of small silicon clusters are determined through exhaustive tight-binding molecular dynamics simulation studies. These simulations revealed that \Si{11}…
Quantum Confinement Effects in Semiconductor Clusters II
Antonietta Tomasulo, Mushti V. Ramakrishna
The band gaps and spectral shifts of CdS, CdSe, CdTe, AlP, GaP, GaAs, and InP semiconductor clusters are calculated from band structure calculations using accurate local and non-lo…
Spectral Shifts of Semiconductor Clusters
Antonietta Tomasulo, Mushti V. Ramakrishnai
The shifts of the electronic absorption spectra of GaAs and GaP semiconductor clusters are calculated using accurate pseudopotentials. In the absence of experimental data at presen…
Structure of Silicon Clusters
Jun Pan, Atul Bahel, Mushti V. Ramakrishna
We determined the structures of silicon clusters in the 11-14 atom size range using the tight-binding molecular dynamics method. These calculations reveal that \Si{11} is an icosah…
Structure of Si12 Cluster
Atul Bahel, Mushti V. Ramakrishna
Tight-binding molecular dynamic simulations have revealed that Si is an icosahedron with all atoms on the surface of an approximately 5 Å~ diameter sphere. This is the most…
