The ultimate goal in molecular electronics is to use individual molecules as the active electronic component of a real-world sturdy device. For this concept to become reality, it will require the field of single-molecule electronics to shift towards the semiconducting platform of the current microelectronics industry. Here, we report silicon-based single-molecule contacts that are mechanically ...

Spiral inductors constructed in Silicon IC technologies possess limited quality factors due to series resistive losses, and losses within the semiconducting substrate. A new model for the less understood substrate losses illustrates how these losses can be minimized, providing quality factor increases of up to 230 percent over un-optimized designs.

In the quest for solutions to meeting future energy demands, solar fuels play an important role. A particularly promising example is photocatalysis since even incremental improvements in performance in this process are bound to translate into significant cost benefits. Here, we report that semiconducting and high surface area 3D silicon replicas prepared from abundantly available diatom fossils...

The low-dimensional electron confinement effects in nanostructures is one of motivation for development of new research areas in growth technologies and materials engineering. To test this fundamental concept, one-dimentional nanostructures, such as nanotubes and nanowires stay good candidates. Thus nanoelectronics is certainly now the branch with the most significant commercial impact as predi...

In recent years DNA-sensors, and generally biosensors, with semiconducting transducers were fabricated and characterized. Although the concept of so-called BioFETs was proposed already two decades ago, its realization has become feasible only recently due to advances in process technology. In this paper a comprehensive and rigorous approach to the simulation of silicon-nanowire DNAFETs at the f...

The breakthrough of the well-known scaling barriers for silicon CMOS logic and memory chip technology would demands intensive research not only on the innovative “topdown” process technologies, but also into the “bottom-up” nanotechnology for nanomaterials and innovative device architectures. In this paper, we explore the chemical synthesis of 1-D inorganic semiconducting nanowires and the corr...

We present a method of selectively removing metallic single-walled carbon nanotubes (SWCNTs) from as-grown arrays on quartz substrates. The process utilizes an external silicon piece as a temporary global top gate to increase the resistance of the semiconducting SWCNTs while current is passed through the metallic SWCNTs, causing electrical breakdown through joule heating. The resulting SWCNT fi...

The interface between photoactive biological materials with two distinct semiconducting electrodes is challenging both to develop and analyze. Building off of our previous work using films of photosystem I (PSI) on p-doped silicon, we have deposited a crystalline zinc oxide (ZnO) anode using confined-plume chemical deposition (CPCD). We demonstrate the ability of CPCD to deposit crystalline ZnO...
