Abstract

Recently, the long-range spin-selective transport in chiral molecules has been investigated for bio-spintronics. The experimental results for a natural metalloprotein molecule suggested a high spin selectivity. I performed first-principle calculations of electron spin transport in a natural metalloprotein molecule based on the Landauer formula. A gold–metalloprotein–gold device model was used to confirm the high spin polarization. There was a relatively large spin density at some amide groups in the helical peptide structures. Furthermore, a large spin density of iron atoms enhanced the spin density of the neighboring coordinated atoms, resulting in spin polarization in the whole molecule. [ABSTRACT FROM AUTHOR]

Abstract

The electrical properties of homogenous organic semiconductive thin films grown by radio frequency plasma polymerization of 3,4,9,10-perylenetetracarboxcyclic dianhydride were investigated. The results showed that the conductivity of the samples prepared with a rf power of 60 W was lower by three orders of magnitude than those prepared with a rf power of 10 W. In addition, exposure to air decreased conductivity.
