  1. 1. Properties of III-V/Si heterojunction fabricated by HVPE

    University essay from KTH/Tillämpad fysik

    Author : Prakhar Bhargava; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  4. 3. Ice condensation as a planet formation mechanism

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Katrin Ros; [2012]
    Keywords : Physics and Astronomy;

    Abstract : 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.
