Micro and Nanotechnology research for you

Science Week in November

During the Science Week in November, the "Zenon Navarro" Microelectronics Museum Space of IMB-CNM will be open for visits.

The 23rd Science Week in Catalonia will be held from 9th to 18nd November, and the Science and Technology Week at CSIC will be held during all November.

IMB-CNM will have “Open Doors” at the Zenon Navarro Museum Space from 12th to 16th November, from 10 h to 13 h and from 15 h to 17 h.

Group visits (more than 10 persons) require a reservation (please contact: This email address is being protected from spambots. You need JavaScript enabled to view it.).

IMB-CNM talks: Inkjet-printed devices for chemo-/biosensing applications

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
31/10/2018 11:00 a.m.

Abstract: Inkjet printing is a nascent technology that is evolving from text and graphic printing into a major topic of scientific research and R&D, where it can be used as a highly reproducible non-contact patterning technique to deposit liquid functional materials at high speed on either small or large areas of flexible and non-flexile substrates. It is a low cost technique because minimizes the waste products and reduces the process steps. The development of organic materials such as polymers with electrical features has boosted the fabrication of new organic printed electrical devices.
In this framework, the talk is devoted to the development of two novel organic devices for chemo-biosensing applications for a low-cost cost devices using inkjet printing technology. The first sensor is an inkjet-printed Metal-Insulator-Semiconductor (MIS) diode. Its simple fabrication process of these diodes also makes it advantageous for scaling up to roll-to-roll production. Moreover, it has been shown that the MIS diode shows a good selectivity to detect NO2. The second sensor is based on Biological Field-Effect Transistor (BioFET). This device was fabricated and optimized to operate correctly under aqueous media and to detect biomolecules.

Jornada pre-llançament sonda BEPICOLOMBO a Mercuri

El Grup de Dispositius i Sistemes de Potència de l’Institut de Microelectrònica de Barcelona – Centre Nacional de Microelectrònica (IMB-CNM) del Consell Superior d’Investigacions Científiques (CSIC), ha desenvolupat i fabricat un dels components electrònics més crítics de la missió conjunta BepiColombo entre l’Agència Europea de l’Espai (ESA) i de l’Agència Japonesa de l’Espai (JAXA). Aquesta missió té com a objectiu l’estudi aprofundit del planeta Mercuri i té previst situar en òrbita del planeta dues sondes d’exploració que hi arribaran d’aquí 7 anys.
El proper dissabte 20 d’octubre de 2018 a les 1:45 UTC està previst el llançament de la missió BepiColombo des de la base de llançament de Kourou a bord d’un Ariane-V. Per aquest motiu el proper divendres dia 19 d’octubre a partir de les 12h, es realitzaran dues xerrades sobre els reptes tecnològics que ha suposat la missió.

 

IMB-CNM talks: Reliability testing methodology and lifetime modelling - Prof. Zoubir Khatir

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
16/10/2018 12:00 a.m.

Abstract: Lifetime reliability testing of power electronic devices by using power cycling tests is required to build up lifetime models. With them, the power devices remaining useful lifetime can be assesed to practice predictive maintenance. In this sense, recent experimental works carried out at IFSTTAR will be presented, such as reliability testing methodologies, aging strategies, methods for failure mechanisms separation, and cumulative degradation assessment. Some specific results on WBG devices (GaN HEMTs) will be described. Finally, modeling aspects will be discussed, like building lifetime models based on electro-thermo-mechanical stresses and material degradations.

IMB-CNM talks: ARRAYS OF PLASMONIC NANOSTRUCTURES WITH HIGH ABSORPTION AND EXTENDED TIME RESPONSE - Ana Conde Rubio

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
07/09/2018 11:30 a.m.

Abstract: In this talk, I will show the fabrication, simulation and optical characterization of three hexagonal lattices of Au nanoelements with high absorption and a slow dynamic response. These systems were fabricated by Electron Beam Lithography (EBL) with small gaps between neighboring elements to exploit near-field coupling. Besides, a metal-insulator-metal configuration was used to enhance absorption of light. Both the simulations and the experimental results demonstrate that these systems behave as perfect absorbers in the visible and/or the near infrared. Besides, the numerical study of the time evolution shows a relatively extended time response over which the systems fluctuates between localized and collective modes. It is of particular interest the echoed excitation of surface lattice resonance modes, which are still present at long times as a consequence of the geometric frustration induced by the geometry of these systems. Hence, these structures could be of interest for enhanced spectroscopies such as Raman photoluminescence or other applications related to light absorption. As a matter of fact, preliminary results have proved their usefulness as substrates for Surface Enhanced Raman Spectroscopy (SERS).
