(Université de Liège) ; van Hulst, Niek F.. (Institut de Ciències Fotòniques) ; Tielrooij, Klaas-Jan (Institut Català de Nanociència i Nanotecnologia)
Diffusion is one of the most ubiquitous transport phenomena in nature. Experimentally, it can be tracked by following point spreading in space and time. Here, we introduce a spatiotemporal pump-probe microscopy technique that exploits the residual spatial temperature profile obtained through the transient reflectivity when probe pulses arrive before pump pulses.

Departament d'Enginyeria Electrònica) ; Nafría i Maqueda, Montserrat (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica)
Random Telegraph Noise (RTN) and Bias Temperature Instabilities (BTI) are two mechanisms that can significantly reduce the performance and reliability of integrated circuits. In scaled devices, both phenomena are stochastic, so that a statistical analysis is required to accurately evaluate their impact on a particular technology. [...]

6 p, 1.6 MB A study on free-standing 3C-SiC bipolar power diodes / Li, Fan (University of Warwick. School of Engineering) ; Renz, Arne Benjamin (University of Warwick. School of Engineering) ; Perez-Tomas, Amador (Institut Català de Nanociència i Nanotecnologia) ; Shah, Vishal (University of Warwick. School of Engineering) ; Gammon, Peter (University of Warwick. School of Engineering) ; La Via, Francesco (Consiglio Nazionale delle Ricerche. Instituto per la Microelettronica e Microsistemi) ; Jennings, Mike (Swansea University. College of Engineering) ; Mawby, Philip (University of Warwick. School of Engineering)
A low p-n built-in potential (1. 75 V) makes 3C-SiC an attractive choice for medium voltage bipolar or charge balanced devices. Until recently, most 3C-SiC had been grown on Si, and power device fabrication had, therefore, been hindered by issues, such as high defect density and limited processing temperature, while devices were necessarily limited to lateral structures.

43 p, 2.6 MB Systematic review of animal-based indicators to measure thermal, social, and immune-related stress in pigs / Guevara, Raúl David (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Pastor Milán, Josep (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Manteca Vilanova, Xavier (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Tedo, Gemma (Lucta S.A. Innovation Division) ; Llonch, Pol (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments)
The intense nature of pig production has increased the animals' exposure to stressful conditions, which may be detrimental to their welfare and productivity. Some of the most common sources of stress in pigs are extreme thermal conditions (thermal stress), density and mixing during housing (social stress), or exposure to pathogens and other microorganisms that may challenge their immune system (immune-related stress).
