—We present temperature-dependent electrical characteristics of vertically aligned carbon nanofiber (CNF) arrays for on-chip interconnect applications. The study consists of three parts. First, the electron transport mechanisms in these structures are investigated using I–V measurements over a broad temperature range (4.4 K to 350 K). The measured(More)
On-chip interconnects fabricated using copper damascene technology have provided the performance necessary to keep pace with the International Technology Roadmap for Semiconductors (ITRS) [1] since the adoption of copper as a replacement for aluminum-based wiring schemes. As microelectronics moves towards the 45 nm node and beyond, however, a multitude of(More)
A method to realize room-temperature operation of a multifrequency Er-doped fiber laser with low-frequency shift feedback placed within a linear laser cavity is theoretically proposed and experimentally demonstrated. Simultaneous multiwavelength lasing with 0.5 nm wavelength spacing is experimentally demonstrated by applying a sinusoidal signal of 10 kHz to(More)
Recent fundamental studies have given rise to the emergence of new applications for carbon-based nanostructures in electrical and biological systems.

Nanostructure characterization of carbon nanofibers (CNFs) for on-chip interconnect applications is presented. We propose a novel technique for characterizing interfacial nanostructures of vertically aligned CNFs, optimally suited for cross-sectional imaging with scanning transmission electron microscopy (STEM). Using this technique, vertically aligned CNFs(More)

Heat generation in carbon nanofibers (CNF) has raised concerns regarding reliability in these structures under high- current conditions. This work addresses the interplay between electron transport and resulting Joule heating in CNFs. The model relates current to power dissipation leading to temperature rise in the structure, thus elucidating the(More)
