Room temperature single electron effects in a Si nano-crystal memory
IEEE Electron Device Letters, 1999Co-Authors: Ilgweon Kim, Sangyeon Han, Jong-ho Lee, Kwangseok Han, Hyungcheol ShinAbstract:An MOS memory based on Si nano-crystals has been fabricated. We have developed a Repeatable Process of forming uniform, small-size and high-density Si nano-crystals and spherical nano-crystals of about 4.5 nm in diameter with density of 5/spl times/10/sup 11//cm/sup 2/ were obtained. Threshold voltage shift of 0.48 V corresponding to single electron storage in individual nano-crystals is obtained. For the first time, room temperature single electron effects are observed. These prove the feasibility of practical Si nano-crystal memory.

Room temperature single electron effects in Si quantum dot memory with oxide-nitride tunneling dielectrics
International Electron Devices Meeting 1998. Technical Digest (Cat. No.98CH36217), 1Co-Authors: Ilgweon Kim, Sangyeon Han, Hyungsik Kim, Jong-ho Lee, Bumho Choi, Sungwoo Hwang, Doyeol Ahn, Hyungcheol ShinAbstract:We have developed a Repeatable Process of forming uniform, small-size and high-density Si quantum dots on oxide-nitride tunneling dielectrics and have fabricated an EEPROM which showed room temperature single electron effects. This proved the feasibility of practical Si quantum dot memory with ON film.

Development of zinc phosphide as a p-type absorber
2012 38th IEEE Photovoltaic Specialists Conference, 2012Co-Authors: Parag Vasekar, Siva P. Adusumilli, Daniel Vanhart, Tara P. Dhakal, Seshu DesuAbstract:In the present contribution, we report a simple and Repeatable Process for the synthesis of zinc phosphide on two different substrates, zinc foil and zinc evaporated on molybdenum-coated glass. Zinc phosphide has been an important candidate for optoelectronic applications and has also been explored in the lithium ion batteries. Zinc phosphide is synthesized from earth-abundant constituents, zinc and phosphorous. Trioctylphosphine (TOP) is used as a source of phosphorous which reacts with zinc and results in the growth of zinc phosphide. Zinc phosphide has been successfully synthesized in both continuous thin film and nanowires form around ∼ 350°C. The synthesized zinc phosphide phase was characterized using SEM, EDS, XRD and XPS. Possible growth mechanism is discussed.

Development of Zinc Phosphide as an Absorber Using Chemical Reflux Technique.
MRS Online Proceedings Library, 2011Co-Authors: Siva P. Adusumilli, Parag Vasekar, Daniel Vanhart, Tara Dhakal, Charles R. Westgate, Seshu DesuAbstract:Recent trend in thin film solar cells is to use earth abundant materials such as zinc and iron. Zinc phosphide (Zn_3P_2) has been has been explored as a choice for solar cell absorber and is currently reviving attention. Zinc phosphide is synthesized from earth-abundant constituents. We have already optimized zinc phosphide phase both in nanocrystalline and bulk thin film form. The purpose of this study is to study growth conditions at different temperatures. In this study, Trioctylphosphine (TOP) is used as a source of phosphorous which reacts with zinc and results in the growth of Zn_3P_2. The synthesized zinc phosphide phase has been characterized using SEM, EDS, XRD and XPS. We report a simple and Repeatable Process for synthesis of Zn_3P_2 phase.

designing mobile information services user requirements elicitation with gss design and application of a Repeatable Process
Hawaii International Conference on System Sciences, 2004Co-Authors: Den M Hengst, E Van De Kar, Jaco H AppelmanAbstract:The main challenge in the first phase of designing mobile services is eliciting user requirements. We propose a Repeatable Process for eliciting user requirements based on the literature on requirements engineering and group support systems. We applied the Repeatable Process in three sessions to elicit user requirements for a mobile information service on a UMTS testbed. The sessions resulted in ideas for services that are highly valued by potential users and criteria for when they can or can not use the service.

Using a predefined passphrase to evaluate a speaker verification system
Artificial Intelligence Research, 2014Co-Authors: Jonathan Leet, John Gibbons, Charles C. Tappert, Vinnie MonacoAbstract:This article presents a standardized and Repeatable Process used to evaluate the performance of a speaker verification system.Through the use of a common passphrase and a subset of extracted feature vectors that outperforms other combinations, thestudy limits the exposure to potential experimental flaws, while measuring true biometric performance more effectively thanexisting evaluation methodologies. After collecting a dataset of 33 participants, the researchers achieved a performance rate of99.8% for the 22 users who contributed at least 20 text-dependent samples. The primary focus of the research, however, was toillustrate a variety of testing techniques that can be used to efficiently analyze the performance of a speaker verification systemand advocate the use of a common passphrase in this Process.
