Advanced methods in Glancing Angle Deposition to control thin film morphology, microstructure and texture
DownloadSpring 2014
Structuring of material on the nanoscale is enabling new functional materials and improving existing technologies. Glancing angle deposition (GLAD) is a physical vapor deposition technique that enables thin film fabrication with engineered columnar structures on the (10 to 100) nm scales. In this...

Development of MEMS-based Piezoresistive Three Dimensional Stress/Strain Sensor with Temperature Compensation
DownloadSpring 2020
In this research, a developed n-type piezoresistive three dimensional (3D) stress sensor with full temperature compensation is presented. The proposed sensing rosette benefits from the stress insensitivity of the full-circular n-type piezoresistor, oriented over (111) silicon plane, to detect...

Nanophotonic Enhancement and Improved Electron Extraction in Perovskite Solar Cells Using Near-Horizontally Aligned TiO2 Nanorods
Download2018-11-18
Thakur, Ujwal K., Zeng, Sheng, Kumar, Pawan, Patel, Sahil, Kisslinger, Ryan, Zhang, Yun, Kar, Piyush, Goswami, Ankur, Thundat, Thomas, Meldrum, Alkiviathes, Shankar, Karthik
While vertically oriented metal oxide nanowires have been intensely researched for use as electron transport layers (ETLs) in halide perovskite solar cells (HPSCs), horizontal nanowires (oriented roughly parallel to the substrate) have received much less attention despite their higher photonic...

Optimizing rooftop solar PV systems in urban regions considering economic and environmental aspects
DownloadFall 2022
In recent years, utilization of photovoltaic (PV) solar systems in built-up regions have received more attention due to global warming issues and the significance of sustainable development. The rooftops of buildings are considered highly suitable for installing PV modules to harvest solar energy...

Fall 2013
Terahertz spectroscopy is a powerful non-contact technique to study the optical and electric properties of materials at sub-picosecond time scales. In this study, ultrafast time-resolved terahertz spectroscopy was performed on both silicon-on-sapphire (SOS) and iron pyrite (FeS2) nano-crystalline...

Utilization of Semiconductors Piezoresistive Properties in Mechanical Strain Measurements under Varying Temperature Conditions for Structural Health Monitoring Applications
DownloadSpring 2013
Strain gauges have been powerful tools in experimental stress analysis. This importance is expected to continue, even though other means of strain measurement are continually introduced to the market. The strain gauge is a simple device that can be easily installed to measure mechanical strain....
