1. Inkjet printed piezoelectric energy harvesters based on self-assembly of diphenylalanine peptide
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Diphenylalanine peptide (Phe-Phe or FF) is a very promising bio-material in the future wearable electronics application due to its self-assembly into nanotubes and nanoribbons with high shear piezoelectric coefficient which is comparable to traditional inorganic piezoelectric materials. In order to efficiently harvest piezoelectric response, alignment and unidirectional polarization of FF nanotubes are required. READ MORE

5. Fabrication and characterisation of RGB LEDs based on nanowire technology
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. READ MORE
