Electrical properties of silver selenide (Ag2Se) thin film, which is a thickness of 500 nm, were studied using conducting atomic force microscopy (c-AFM). A resistive switching was observed in the sweep voltage range from −7 to +7 V at room temperature. In addition, the Ag/Ag2Se/Au structure was compared with the Ag2Se/Au structure. It was considered that the resistive switching behavior may cause...
The excellent mechanical properties of carbon nanotubes (CNTs), such as low density, high stiffness, and great strength make them ideal candidates for reinforcement material in a wide range of high performance materials applications. The strength-to-weight ratio of CNT fibers are anticipated to exceed any materials currently available, yet theoretical calculations indicate that they still do not take...
The unique mechanical, electrical, and thermal properties of carbon nanotube (CNT) molecules place them at the forefront of nanotechnology. The mechanical properties of carbon nanotubes such as high tensile strength and modulus provide an effective pathway for better construction materials. Before this potential can be realized, effective techniques of creating load transfer in bulk material must...
Reportedly, molecular wires which have intrinsically different characteristics from semiconductor nano wires show some unique transport properties. However, it seems that there is not so much understanding about their local properties. So, in this work, we characterized electrical properties of carotenoid which had differently substituted end-groups by using Scanning Probe Microscopy. To confirm the...
Using an AFM with a conducting cantilever, the current versus voltage (I-V) characteristics of carotenedithiol molecular wires which have different end groups are measured. An Au nanoparticle is attached to each molecule via the protruding thiol group and a PtIr coated AFM probe is used as an electrode to contact with the molecule through the Au nanoparticle. Then it was reconfirmed by the I-V measurement...
