Disordered nanowire based photovoltaics
In this paper we present experimental results incorporating traditional amorphous silicon (a-Si) photovoltaic devices with a three-dimensional, disordered nanowire (NW) mat using approaches that are compatible with current large area…

Atomic layer deposition of Al2O3 for top-gated organic transistors
We have developed an oxide growth process for a top-gate transistor architecture for organic thin film semiconductors based on the ALD process, plasma-enhanced as well as thermal.

Density of electronic states model for organic solar cells
Data from electronic transport, photoconductivity spectral response and theoretical calculations are described, and we show that these provide consistent and quantitative information about the electronic structure.

Enhancing cyber-physical security through data patterns
In this position paper, we propose a data-driven approach for security management in a network that interacts or receives inputs from physical systems - including human behavior.

Domain-specific Assessment: What Foundational Concepts and Reasoning Skills are Community College Students Learning?
The Domain-Specific Assessment project developed a set of tools and assessment items that measure students’ capacity to apply knowledge rather than simply memorize vast amounts of it.

The Design Pattern: A Blueprint for a New Domain-specific Assessment
Assessment researchers at SRI International in Menlo Park, CA, designed a prototype scenario-based assessment to measure how well college students learn the big ideas of biology and economics and how…
