  1. 1. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lun Sang; [2018]
    Keywords : ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

    Abstract : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. READ MORE

  2. 2. Theoretical optimization of solar electricity using a DC-microgrid

    University essay from Lunds universitet/Avdelningen för Byggnadsfysik

    Author : Manuela Stierna Fernandez; [2018]
    Keywords : Technology and Engineering;

    Abstract : This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid.

  3. 3. Fabrication of Tunneling Field Effect Transistors (TFETs) and the study of graphene

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Carlos Nunez Lobato; [2018]
    Keywords : graphene; semiconductor; exfoliation; boron nitride; Physics and Astronomy;

    Abstract : After the discovery of graphene in 2004, a single layer of graphite, the assembly of 2D materials became a promising research area in solid state Physics. This thesis explores fabrication of 2D-heterostructures that aim to probe into graphene’s electronic structure with the Tunneling Field Effect Transistor (TFET). READ MORE

  4. 4. Glare from photovoltaic systems

    University essay from Lunds universitet/Energi och ByggnadsDesign

    Author : Erik Hjorth; Florian Wochele; [2017]
    Keywords : Technology and Engineering;

    Abstract : With an increasing usage of photovoltaic panels also in urban context the cases of glare caused by photovoltaic systems are raising. Many countries have low or no regulations regarding outdoor glare caused by daylight, therefore legal cases can be complicated. READ MORE

  5. 5. Demand Response in the Engineering Industry : Based on a case study of Volvo Powertrain Production in Köping

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Matilda Grawé; [2017]
    Keywords : Demand Response; Engineering Industry; Tariff Analysis;

    Abstract : The climate change is driving a change in technology and promotes intermittent electricity; solar and wind, and also promotes new technology such as electrical vehicles. The increased share of intermittent  power and changed patterns of using power causes large strain on the powergrids during critical hours of the year. READ MORE
