The structural and electronic properties of armchair and zigzag models of single-wall GaN nanotubes have been investigated by performing semi-empirical molecular orbital self-consistent field calculations at the level of PM3 method within the RHF formulation. It has been found that these structures are stable and endothermic. The armchair model has zero net dipole moment, whereas the zigzag model has nonzero net dipole moment. It has been found that GaN armchair tube with even number of hexagonal rings on the circumference has more excess charge on it and thus this tube may have better conducting properties, they may be candidates to be used as good conducting nanowires.

Structural and electronic properties of guanine and guanosine
Erkoc, F; Erkoç, Şakir (Elsevier BV, 2002-08-16)
The structural and electronic properties of guanine and guanosine have been investigated theoretically by performing semi-empirical and ab initio molecular orbital theory calculations. The geometry of the systems have been optimized considering the semi-empirical molecular orbital theory at the level of Austin model 1, and the electronic properties of the systems have been calculated by ab initio restricted Hartree-Fock with including full MP2 correlation correction in their ground state.
Structural and electronic properties of ajoene molecule
Erkoç, Şakir; Sumer, S; Erkoc, F (Elsevier BV, 2003-08-01)
The structural and electronic properties of ajoene molecule have been investigated theoretically by performing semi-empirical molecular orbital theory calculations. The geometry of the system has been optimized and the electronic properties of the system considered has been calculated by semiempirical self-consistent-field molecular orbital theory at the AMI level within RHF formalism in its ground state.
Structural and electronic properties of HEME and HEME-X; X = O-2, CO, NO
Erkoç, Şakir; Erkoc, F (Elsevier BV, 2001-07-16)
The structural and electronic properties of HEME and HEME-X (X = O-2, CO, NO) have been investigated theoretically by performing semi-empirical molecular orbital theory at the level of PM3 calculations. The optimized structure and the electronic properties of the molecules are obtained.
Structural and electronic properties of 'benzorods'
Erkoc, F (Elsevier BV, 2003-11-03)
The structural and electronic properties of benzorods, carbon nanorods made of benzen molecules, have been investigated systematically by performing semi-empirical self-consistent-field molecular-orbital theory calculations at AM1-RUF level. The benzorod represented by nC6 contains n benzonoid rings placed parallel to each other forms a stable structure.
Structure and electronic properties of heterofullerene C30B15N15
Erkoç, Şakir (Elsevier BV, 2004-09-27)
Structure and electronic properties of heterofullerene C30B15N15 has been investigated theoretically by performing semi-empirical molecular orbital calculation at PM3 level within RHF formalism and density functional theory at B3LYP level including MP2 correlation correction. The structure has been found stable in the ground state but endothermic. The isolated C30B15N15 has a net dipole moment value of about 3 Debyes, and frontier molecular orbital energy gap value of about I eV. These properties make this ...
