  2. 2. Integration of thulium silicate for enhanced scalability of high-k/metal gate CMOS technology

    Author : Eugenio Dentoni Litta; Per-Erik Hellström; Mikael Östling; Lars-Åke Ragnarsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thulium; silicate; TmSiO; Tm2O3; interfacial layer; IL; CMOS; high-k; ALD; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : High-k/metal gate stacks have been introduced in CMOS technology during the last decade in order to sustain continued device scaling and ever-improving circuit performance. Starting from the 45 nm technology node, the stringent requirements in terms of equivalent oxide thickness and gate current density have rendered the replacement of the conventional SiON/poly-Si stack unavoidable.

  3. 3. Valence-Level Dependent Presentation-Order Effects in Preference Judgments

    Author : Mats P. Englund; Åke Hellström; William M. Petrusic; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preference judgment; order effects; stimulus valence; sensation weighting; feature matching; comparison direction; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Reversal of the stimulus-presentation order often affects the outcome in paired stimulus comparison. Psychophysicists have found that the size and direction of the order effects depend on the compared stimuli’s magnitudes, but this magnitude dependence does not seem to have been recognized previously in cognitive research on preference judgment.

  4. 4. Expecting Happy Women, Not Detecting the Angry Ones : Detection and Perceived Intensity of Facial Anger, Happiness, and Emotionality

    Author : Tonya S. Pixton; Åke Hellström; Maria Larsson; James A. Russell; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Signal Detection Perception ; Happiness; Anger; Face Perception; Facial Expressions; Superiority Effects; Gender Differences; Response Bias; Scaling; Euclidean Distance; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Faces provide cues for judgments regarding the emotional state of individuals. Using signal-detection methodology and a standardized stimulus set, the overall aim of the present dissertation was to investigate the detection of emotional facial expressions (i.e., angry and happy faces) with neutral expressions as the nontarget stimuli.
