  3. 2. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Jennifer Silander; [2022]
    Keywords : Optical properties; transmittance; FTIR spectrometry; scanning electron microscopy; x-ray diffraction; metal-insulator transition; crystalline material; sol-gel; spin-coating; vanadium oxide; infrared light;

    Abstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE

  4. 3. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joacim Sundh; [2022]
    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  5. 4. Operation Oriented Digital Twin of Hydro Test Rig

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik
