n and p type character of single molecule diodes
Looking for single molecule electronic devices, we have investigated the charge transport properties of individual tetra-phenylporphyrin molecules on different substrates by ultrahigh-vacuum scanning tunneling microscopy and spectroscopy and by first-principles calculations. The tetra-phenylporphyrins with a Co atom (Co-TPP) or 2 hydrogens (H2-TPP) in the central macrocycle when deposited on Cu...

Single-character type identification
Different character recognition problems have their own specific characteristics. The state-of-art OCR technologies take different recognition approaches, which are most effective, to recognize different types of characters. How to identify character type automatically, then use specific recognition engines, has not brought enough attention among researchers. Most of the limited researches are ...
متن کاملNanoscale Diodes Without p-n Junctions
The p-n junction cannot be implemented at the nanoscale because the doping is very often a detrimental effect. The doping could change dramatically the properties of a nanomaterial such as graphene or single-walled carbon nanotubes. Therefore, we will present two graphene diodes without a p-n junction. The first is based on the dissimilar metals having workfunction below and above the graphene ...
متن کاملTransparent p-n Heterojunction Thin Film Diodes
Transparent p-n heterojunction diodes are fabricated using p-type CuYO2:Ca and n-type ZnO:Al thin films on a glass substrate coated with indium-tin oxide (ITO). The contact between the n-ZnO:Al / p-CuYO2:Ca heterojunction is found to be rectifying, while the ITO / ZnO:Al contact is ohmic. The typical ratio of forward to reverse current is 15 in the range -3 to 3V. The diode current-voltage char...
