1. 1. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Aidas Urbonavicius; [2023]
   Keywords : ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

   Abstract : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. READ MORE

3. 2. The design of evacuation alarms for people who are deaf or hard of hearing

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Anastasia Afanasova; [2023]
   Keywords : Alarm system; Deaf people; Hard-of-hearing people; Fire safety.; Technology and Engineering;

   Abstract : The ability to hear is essential for receiving auditory signals, which serve as warnings and alerts in many situations, including fire evacuation. However, people with hearing impairments may miss out such signals and can be exposed to dangerous situations. READ MORE

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Mattéo Hochart; [2023]
   Keywords : Technology and Engineering;

   Abstract : Context: The CardioHolter, developed by Kaunas Institute of Technology, Lithuania, has been used in previous studies on cardiovascular behavior at the Department of Biomedical Engineering at Lund University. This equipment associates two finger photoplethysmography (PPG) sensors and an electrocardiogram (ECG) sensor. READ MORE

5. 4. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

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

   Author : Sofie Johannesson; Sebastian Skog; [2022]
   Keywords : Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

   Abstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).
