Shaped single-voltage poling pulses were applied to electrode structures that were fabricated by a combination of electron-beam and direct-writing laser lithography.

Nano-ridge engineering is a new approach that enables the integration of III–V based devices on trench-patterned Si substrates with very high crystal quality. Using selective area growth, the III–V material is deposited into narrow trenches to reduce the dislocation defect density by aspect ratio trapping. The growth is continued out of the trench pattern and a box-shaped III–V nano-ridge is engineered by adjusting the growth parameters. A flat (001) GaAs nano-ridge surface enables the epitaxial integration of a common InGaAs/GaAs multi-quantum-well (MQW) structure as an optical gain medium to build a laser diode. In this study, a clear correlation is found between the photoluminescence (PL) lifetime, extracted from time-resolved photoluminescence (TRPL) measurements, with the InGaAs/GaAs nano-ridge size and defect density, which are both predefined by the nano-ridge related pattern trench width. Through the addition of an InGaP passivation layer, a MQW PL lifetime of up to 800 ps and 1000 ps is measured when pumped at 900 nm (only QWs were excited) and 800 nm (QWs + barrier excited), respectively. The addition of a bottom carrier blocking layer further increases this lifetime to ∼2.5ns (pumped at 800 nm), which clearly demonstrates the high crystal quality of the nano-ridge material. These TRPL measurements not only deliver quick and valuable feedback about the III–V material quality but also provide an important understanding for the heterostructure design and carrier confinement of the nano-ridge laser diode."}],"status":"public","publication":"Journal of Applied Physics","type":"journal_article","title":"Time-resolved photoluminescence characterization of InGaAs/GaAs nano-ridges monolithically grown on 300 mm Si substrates","doi":"10.1063/1.5139636","date_updated":"2025-04-25T07:28:42Z","publisher":"AIP Publishing","volume":127,"date_created":"2025-04-25T07:18:24Z","author":[{"first_name":"Yuting","last_name":"Shi","full_name":"Shi, Yuting"},{"full_name":"Kreuzer, Lisa C.","last_name":"Kreuzer","first_name":"Lisa C."},{"first_name":"Nils Christopher","last_name":"Gerhardt","orcid":"0009-0002-5538-231X","id":"115298","full_name":"Gerhardt, Nils Christopher"},{"last_name":"Pantouvaki","full_name":"Pantouvaki, Marianna","first_name":"Marianna"},{"last_name":"Van Campenhout","full_name":"Van Campenhout, Joris","first_name":"Joris"},{"full_name":"Baryshnikova, Marina","last_name":"Baryshnikova","first_name":"Marina"},{"first_name":"Robert","last_name":"Langer","full_name":"Langer, Robert"},{"first_name":"Dries","last_name":"Van Thourhout","full_name":"Van Thourhout, Dries"},{"first_name":"Bernardette","last_name":"Kunert","full_name":"Kunert, Bernardette"}],"year":"2020","intvolume":"       127","citation":{"apa":"Shi, Y., Kreuzer, L.

Second-harmonic (SH) microscopy allows for the noninvasive visualization and analysis of ferroelectric domain structures and walls. While the technique is well understood in bulk lithium niobate, SH microscopy in thin films is largely influenced by interfacial reflections and resonant enhancements, which depend on film thicknesses and substrate materials. We present a comprehensive analysis of SH microscopy in x-cut lithium niobate thin films, based on a full three-dimensional focus calculation and accounting for interface reflections. We show that the dominant signal in backreflection originates from a copropagating phase-matched process observed through reflections, rather than direct detection of the counterpropagating signal as in bulk samples. We simulate the SH signatures of domain structures by a simple model of the domain wall as an extensionless transition from a −χ(2) to a +χ(2) region. This allows us to explain the main observation of domain structures in the thin-film geometry, and, in particular, we show that the SH signal from thin poled films allows to unambiguously distinguish areas, which are completely or only partly inverted in depth."}],"publication":"Journal of Applied Physics","doi":"10.1063/1.5113727","main_file_link":[{"url":"https://pubs.aip.org/aip/jap/article-pdf/doi/10.1063/1.5113727/15233243/114105_1_online.pdf","open_access":"1"}],"volume":126,"author":[{"first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","full_name":"Rüsing, Michael","id":"22501"},{"full_name":"Zhao, J.","last_name":"Zhao","first_name":"J."},{"last_name":"Mookherjea","full_name":"Mookherjea, S.","first_name":"S."}],"date_updated":"2023-10-11T07:48:11Z","oa":"1","intvolume":"       126","citation":{"apa":"Rüsing, M., Zhao, J., &#38; Mookherjea, S.

The influence of the 3C-SiC/Si (001) substrate morphology is studied with emphasis on the anti-phase domains (APDs). The GaN nucleation is governed by the APDs of the substrate, resulting in equal plane orientation and the same anti-phase boundaries. The presence of the APDs is independent of the GaN layer thickness. Atomic force microscopy surface analysis indicates lateral growth anisotropy of GaN facets in dependence of the APD orientation. This anisotropy can be linked to Ga and N face types of the {111} planes, similar to observations of anisotropic growth in 3C-SiC. In contrast to 3C-SiC, however, a difference in GaN phase composition for the two types of APDs can be measured by electron backscatter diffraction, μ-Raman and cathodoluminescence spectroscopy."}],"file":[{"content_type":"application/pdf","relation":"main_file","success":1,"creator":"hclaudia","date_created":"2018-08-27T12:42:38Z","date_updated":"2018-08-27T12:42:38Z","file_id":"4147","file_name":"Anti-phase domains in cubic GaN.pdf","access_level":"closed","file_size":3305430}],"publication":"Journal of Applied Physics","ddc":["530"],"language":[{"iso":"eng"}]}]
