A physics-based model is presented that captures the electrical high-frequency behavior of low-dimensional nanostructures used in emerging technologies such as the ultra-high-density capacitor. Derived from transmission line theory the analytical expression provides a frequency-dependent admittance of a lossy nanostructure, which can be numerically integrated over arbitrary areas comprising the nanostructure. Edge effects, a distributed nature of resistivity or dimensions of the nanostructure comprising the device can be taken into consideration and make it a powerful tool for designing future integrated circuits. The model predictions show an excellent match with hardware measurements up to 3 GHz on state-of-the-art carbon nanofiber based MIM-capacitors with capacitance densities up to 500 nF/mm2 at 6 μm device height.
Smoltek holds unique world patents for technologies that make material engineering on an atomic level possible. Smoltek has solutions that allow continued miniaturization and increased performance of semiconductors, contribute to carbon-free steel production and renewable energy storage, and enable mind control of robotic prostheses. This is a story of how Smoltek came to be.
This is the third and last article in a series of three in which Smoltek founder and strategic advisor Shafiq Kabir share his personal thoughts on nanotechnology opportunities. In the previous two articles, he has addressed both the hype and the reality of carbon nanotechnology. In this last article, he looks into the future. He discusses how carbon nanotechnology will unleash the power of the internet of everything.
