1. Properties of III-V/Si heterojunction fabricated by HVPE
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. LÄS MER
2. The fate of pebbles and planetesimals entering protoplanetary envelopes
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Planetary embryos grow by the accretion of solid dust-material, ranging from cm- to m-sized pebbles up to km-sized planetesimals. However, the underlying size-distribution of the accreted material is poorly understood. LÄS MER
3. Ice condensation as a planet formation mechanism
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : In models of dust growth in protoplanetary discs focus is typically on coagulation, a mechanism which unfortunately seems incapable of forming particles larger than centimeters. The main reasons for this are that collisions between larger particles lead to bouncing or fragmentation rather than sticking, and that particles approaching meter-sizes drift radially inwards in the disc due to interaction with the surrounding gas.
