Measurement of Lattice Strain and Relaxation Effects in Strained Silicon Using X-ray Diffraction and Convergent Beam Electron Diffraction

Measurement of Lattice Strain and Relaxation Effects in Strained Silicon Using X-ray Diffraction and Convergent Beam Electron Diffraction

Date: August 2007
Creator: Diercks, David Robert
Description: The semiconductor industry has decreased silicon-based device feature sizes dramatically over the last two decades for improved performance. However, current technology has approached the limit of achievable enhancement via this method. Therefore, other techniques, including introducing stress into the silicon structure, are being used to further advance device performance. While these methods produce successful results, there is not a proven reliable method for stress and strain measurements on the nanometer scale characteristic of these devices. The ability to correlate local strain values with processing parameters and device performance would allow for more rapid improvements and better process control. In this research, x-ray diffraction and convergent beam electron diffraction have been utilized to quantify the strain behavior of simple and complex strained silicon-based systems. While the stress relaxation caused by thinning of the strained structures to electron transparency complicates these measurements, it has been quantified and shows reasonable agreement with expected values. The relaxation values have been incorporated into the strain determination from relative shifts in the higher order Laue zone lines visible in convergent beam electron diffraction patterns. The local strain values determined using three incident electron beam directions with different degrees of tilt relative to the device structure have ...

Measurement of Mood State Changes Throughout a Competitive Volleyball Season

Measurement of Mood State Changes Throughout a Competitive Volleyball Season

Date: May 1995
Creator: Schultes, Bruce A. (Bruce Anthony)
Description: Mood state changes have been assessed in endurance sport athletes such as swimmers, distance runners and rowers. However, much less is known about the psychological changes that occur in team sport athletes. The purpose of this study was to assess mood state changes of intercollegiate female volleyball players across a competitive season.

A Measurement of the Popularity of the Extra-Curricular Activities in Cleburne High School, Cleburne, Texas, with the Relationships of Certain Factors to that Popularity

A Measurement of the Popularity of the Extra-Curricular Activities in Cleburne High School, Cleburne, Texas, with the Relationships of Certain Factors to that Popularity

Date: 1950
Creator: Watson, Katie Maxine
Description: The purposes of this study are: (1) to determine the popularity of extra-curricular organizations existing in the school as a means of indicating the successful and the unsuccessful groups in the school, (2) to establish the relationships of certain factors to the popularity of the activities so that efforts may be made to improve less successful activities, (3) to discover the extent and the popularity of social activities provided by the city of Cleburne, Texas, for the high school students in order that administrators of the school may have more insight into the extent of the need of high school students for social activities sponsored by the school.

The Measurement of the Third-order Elastic Constants for La3ga5sio14 (Lgs) and La3ga55ta05o14 (Lgt) Single Crystal

The Measurement of the Third-order Elastic Constants for La3ga5sio14 (Lgs) and La3ga55ta05o14 (Lgt) Single Crystal

Date: December 2013
Creator: Karim, Md Afzalul
Description: Recently, the development of electronic technology towards higher frequencies and larger band widths has led to interest in finding new piezoelectric materials, which could be used to make filters with larger pass band widths and oscillators with better frequency stability. Langasite (La3Ga5SiO14, LGS) and its isomorphs have enticed considerable attention of researchers as a potential substrate material for piezoelectric device applications because of its high frequency stability and fairly good electromechanical coupling factors for acoustic wave devices. Nonlinear effect including drive level dependence, mode coupling, force-frequency effect and electroelasic effect are critical for the design of these devices. Third-order elastic constants (TOEC) play an important role in a quantitative analysis of these nonlinear effects. In particular these elastic constants are of great importance when the BAW (Bulk Acoustic Wave) and SAW (Surface Acoustic Wave) sensors of force, acceleration and so on are designed. Until now Langasite (LGS) and Langatate (LGT) crystal resonators have been qualified in terms of quality factor, temperature effect, isochronism defect and material quality. One of the most important advantages of those crystals is that they will not undergo phase transitions up to its melting temperature of 1450°. Presently there is no data on TOEC of LGT ...

A Measurement System for Monitoring Play in Typically Developing Children and Children with Autism

A Measurement System for Monitoring Play in Typically Developing Children and Children with Autism

Date: May 2002
Creator: Gudmundsdottir, Kristin
Description: A comprehensive measurement system was developed to monitor play in children with autism and typically developing children. The study was conducted in a preschool operated in conjunction with a center-based program for children with autism. The development of the measurement system was based on observations of four children with autism and three typically developing children during social and play activites. Data were collected on material use and several dimensions of play: Simple Manipulation, Functional Manipulation, Symbolic Toy Play, Symbolic Role Play and Play Themes. The results indicated that the measurement system consistently measured a wide range of play behaviors across children and materials. Significance of the information gathered from the measurement system in assessing play and designing interventions is discussed.

Measures and Correlates of Daily Spiritual Experiences

Measures and Correlates of Daily Spiritual Experiences

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Mirbaha-Hashemi, Fariba
Description: Although a change of religious landscape in America in recent years has been suggested and widely accepted in the social sciences, most studies tend to focus on measures of religiosity and how it is changing. The subject of spirituality and its correlates seem to be mostly ignored. This study utilizes nationally representative data generated for the first time in General Social Survey (GSS) on the subject of spirituality to measure Americans' spirituality and daily spiritual experiences and their most significant correlates. In this study, most Americans (89%) showed to have some degree of spirituality and daily spiritual experiences. Moreover, variables of gender, race/ethnicity, marital status, religious origin, and residence in conservative region when growing up shown to be significant predictors of spirituality.
