We have measured the temperature-dependent thermal conductivity of individual multiwall boron nitride nanotubes using a microfabricated test fixture that allows direct transmission electron microscopy characterization of the tube being measured. is exceptionally sensitive to isotopic substitution, with a 50% enhancement in resulting for boron nitride nanotubes with 99.5% . For isotopically pure boron nitride nanotubes, rivals that of carbon nanotubes of similar diameter.

The conduction band offset (CBO) of SnS as the light absorbing layer and as the buffer layer in SnS thin film solar cells has been optimized to improve the solar cell conversion efficiency. We controlled the CBO experimentally by varying the Mg content (x) of the layer. The optimum CBO value range for improved solar cell performance was determined to be from −0.1 to 0 eV. A SnS thin film solar cell sample with the optimum CBO value exhibited conversion efficiency of approximately 2.1%.

We have characterized the electron transport properties of n-decylamine-functionalized Si nanosheets (NSs) using atomic force microscopy with a conductive cantilever under vacuum conditions at room temperature. Electrons are transported from the cantilever to the substrate through Si NSs. The Si NSs exhibit nonresonant tunneling; the transport mechanisms are based on direct tunneling at low bias voltages and Fowler–Nordheim tunneling at high bias voltages.
About Me
Takashi Ikuno received his Ph.D. degree from Osaka University, Japan, in 2004. From 2004 to 2007, he was a postdoctoral researcher at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory. From 2007 to 2016, he was a senior researcher at Toyota Central R&D Labs. Since 2016, he has been an associate professor at the Tokyo University of Science. His research interests are in carbon-related nanomaterials, energy conversion devices, and environmentally friendly materials and devices.
