    Microstructure of highly p-type doped GaN sub-contact layers for low-resistivity contacts

    The effect of a highly Mg doped subcontact layer on top of GaN grown by metal organic vapor phase epitaxy and its interface to a Pd/Au contact layer was investigated by means of transmission electron microscop...

    Characterization and structuring of nitride-based heterostructures for vertical-cavity surface-emitting lasers

    A new approach for nitride-based distributed Bragg reflectors as mirrors for vertical-cavity surface-emitting lasers was investigated by means of transmission electron microscopy. These layers consisted of mul...
