  1. 6. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Alexandros Bampis; [2023]
    Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER

  3. 7. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Hiruy Michael Weldegiorgish; [2022]
    Nyckelord :Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

    Sammanfattning : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.

  4. 8. Piezoelectric Guitar Tuner

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Albin Boestad; Fabian Rudberg; [2021]
    Nyckelord :Mechatronics Tuner Guitar Piezo Arduino; Mekatronik; Stämmare; Guitar; Piezo Arduino;

    Sammanfattning : This bachelor thesis in Mechatronics account for the process of constructing an automatic guitar tuner by means of a piezo-electric sensor, a stepper motor and Arduinobased control. The E4 - string on an acoustic guitar was used as a proxy for tuning any other possible guitar string. LÄS MER
