Two-step growth of (In,Ga)N pseudo-substrates on GaN templates by plasma-assisted molecular beam epitaxy

Huaide Zhang, Jingxuan Kang, Aidan F. Campbell +3

(In,Ga)N layers are grown by plasma-assisted molecular beam epitaxy on GaN templates. We introduce a two-step protocol that involves switching the growth conditions from initially…

Uniform large-area surface patterning achieved by metal dewetting for the top-down fabrication of GaN nanowire ensembles

Jingxuan Kang, Rose-Mary Jose, Miriam Oliva +6

The dewetting of thin Pt films on different surfaces is investigated as a means to provide the patterning for the top-down fabrication of GaN nanowire ensembles. The transformation…

Phase-selective growth of $κ$ - vs $β$ -Ga $_{2}$ O $_{3}$ and (In $_{x}$ Ga $_{1 - x}$ ) $_{2}$ O $_{3}$ by In-mediated metal exchange catalysis in plasma-assisted molecular beam epitaxy

A. Ardenghi, O. Bierwagen, J. Lähnemann +4

Its piezo- and potentially ferroelectric properties make the metastable kappa polymorph of Ga $_{2}$ O $_{3}$ an interesting material for multiple applications, while In-incorporation int…

Composition and optical properties of (In,Ga)As nanowires grown by group-III-assisted molecular beam epitaxy

M Gómez Ruiz, Aron Castro, Jesús Herranz +5

(In,Ga) alloy droplets are used to catalyse the growth of (In,Ga)As nanowires by molecular beam epitaxy on Si(111) substrates. The composition, morphology and optical properties of…
