  1. 1. Development of Ferroelectric Hafnium Oxide for Negative Capacitance Field Effect Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Robin Atle; [2019]
    Keywords : Un-doped ferroelectricity; HfO2; Hafnium oxide; ALD; Atomic Layer Deposition; Hysteresis; P-E; polarization; Technology and Engineering;

    Abstract : With the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. READ MORE

  2. 2. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Vidar Flodgren; [2019]
    Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

  3. 3. I-V and Optical Characterization of InP/InAsP Quantum Disc-in-Nanowire Infrared Photodetectors

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi
