Vacuum Field Emission Devices With Integrated Cnts, Leo Kheyn-Kheyfets

Journal of the Microelectronic Engineering Conference

This research looks at the design and fabrication of sub 100-nm carbon nanotube-based vacuum field emission devices. The devices in this project are based in the Fowler-Nordheim emission of electrons, which allow the devices to hold radiation hardened capabilities due the absence of a semiconductor channel. On top of the radiation hardened capabilities of the Vacuum FETS, the emitter material, SWCNT (Single-Wall Carbon Nanotubes) themselves hold radiation hardened capabilities. SWCNT could also be the nanomaterial that replaces silicon in CMOS FETs (Field-Effect- Transistors). Through extensive preparation and testing, a field emission device based on carbon nanotube emitters with an effectiv …

Fabrication And Characterization Of Bubble-Driven Micromixers, Matthew David Rolleston

Journal of the Microelectronic Engineering Conference

Microfluidics differ from conventional fluid flows in that viscous forces dominate. As a result, microfluidics offer unprecedented control over fluid flows. The precise manipulation of fluids can be applied anywhere from healthcare in medical diagnostics to pharmaceutical companies miniaturizing reactions to reduce reagent consumption. In order to apply microfluidics as a comprehensive solution, unit operations must be performed such as mixing, sorting and dilution. This work investigates the fabrication and characterization of bubble-driven micromixers using inertial micropump technology. Unlike macroscopic fluid flows with turbulence, transport phenomena become restricted in microfluidics. Active mixing approaches apply external forces (such as thermal or …

Enhanced Boron Activation In Xenon Flash Lamp Annealed Polysilicon Through Pre-Amorphization, Adam Rosenfeld

Journal of the Microelectronic Engineering Conference

Thin film transistors were fabricated to investigate the influence of the addition of a fluorine preamorphization implant on boron activation in the source/drain. The addition of the fluorine resulted in a higher drive current for high dose implants (5x10¹⁵ cm^-2). The higher current as well as an increased calculated mobility supports the hypothesis that fluorine implant increases boron activation. Device performance was noticed to be dependent on its location on the wafer complicating experimental analysis. Additional system control would allow for more direct treatment comparisons.

Social Recommendations For Personalized Fitness Assistance, Saumil Dharia, Magdalini Eirinaki, Vijesh Jain, Jvalant Patel, Iraklis Varlamis, Jainikkumar Vora, Rizen Yamauchi

Faculty Publications

Wearable technology allows users to monitor their activity and pursue a healthy lifestyle through the use of embedded sensors. Such wearables usually connect to a mobile application that allows them to set their profile and keep track of their goals. However, due to the relatively “high maintenance” of such applications, where a significant amount of user feedback is expected, users who are very busy, or not as self-motivated, stop using them after a while. It has been shown that accountability improves commitment to an exercise routine. In this work, we present the PRO-Fit framework, a personalized fitness assistant aiming at …

Implementation Of 5s At A Survey Laboratory In Western Kentucky University, Mercy Akunna Ebuetse

Masters Theses & Specialist Projects

5S is a technique used alongside methodologies such as lean, total quality management and six-sigma for continuous improvement and workplace standardization. Nonetheless, despite the upsurge in the implementation of 5S by lean manufacturing facilities and other industries, educational laboratories appear to be lagging. Taking into consideration the benefits of implementing 5S within industry, it has become crucial to replicate the technique in an educational laboratory to obtain equivalent results. To upgrade educational laboratories into industrial laboratories, 5S (sort, set in order, shine, standardize, and sustain) is required to improve the laboratory’s ergonomics that subsequently increases efficiency, productivity, and lessens waste …
