Bækken, Idun (Master thesis, 2021) -
Correlated Structural and Optical Characterisation of Individual AlGaN Nanowires on Graphene
Hansen, Ingvild (Master thesis, 2019)III-nitrider viser lovende egenskaper for bruk innen ultrafiolette optoelektroniske enheter, men en betydelig utfordring for fremtidig utbedring er lav effektivitet for enheter med kort bølgelengde. Med en økende etterspørsel ... -
Fabricating Si[111] Nanostructures on Graphene by Aluminum-Induced Crystallization for High Yield Vertical III-V Semiconductor Nanowire Growth
Høiaas, Ida Marie (Master thesis, 2014)III-V semiconductor nanowire-graphene photovoltaics is an emerging technology that has the potential of highly efficient, flexible and ultra-thin solar cells. This thesis has explored aluminum-induced crystallization(AIC) ... -
Fabrication of Si(111) crystalline thin film on graphene by aluminum-induced crystallization
Høiaas, Ida Marie; KIM, DONG CHUL; Weman, Helge (Journal article; Peer reviewed, 2016)We report the fabrication of a Si(111) crystalline thin film on graphene by the aluminum-induced crystallization (AIC) process. The AIC process of Si(111) on graphene is shown to be enhanced compared to that on an amorphous ... -
GaN/AlGaN nanocolumn ultraviolet light-emitting diode using double-Layer graphene as substrate and transparent electrode
Høiaas, Ida Marie; Liudi Mulyo, Andreas; Vullum, Per Erik; Kim, Dong Chul; Ahtapodov, Lyubomir; Fimland, Bjørn-Ove; Kishino, Katsumi; Weman, Helge (Journal article, 2019)The many outstanding properties of graphene have impressed and intrigued scientists for the last few decades. Its transparency to light of all wavelengths combined with a low sheet resistance makes it a promising electrode ... -
Graphene-Based Transparent Conducting Substrates for GaN/AlGaN Nanocolumn Flip-Chip Ultraviolet Light-Emitting Diodes
Liudi Mulyo, Andreas; Mukherjee, Anjan; Høiaas, Ida Marie; Ahtapodov, Lyubomir; Nilsen, Tron Arne; Toftevaag, Håvard Hem; Vullum, Per Erik; Kishino, Katsumi; Weman, Helge; Fimland, Bjørn-Ove (Journal article; Peer reviewed, 2021)Flip-chip ultraviolet light-emitting diodes based on self-assembled GaN/AlGaN nanocolumns have been fabricated, exploiting single-layer graphene not only as a growth substrate but also as a transparent conducting electrode. ... -
Microprobing of nanowire-based LEDs down to single nanowire level inside a FIB-SEM
Raen, Knut Håvard (Master thesis, 2021) -
Semiconductor-graphene hybrid structures and optoelectronic devices
Høiaas, Ida Marie (Doctoral theses at NTNU;2020:258, Doctoral thesis, 2020)In order to utilise the intriguing properties discovered in nanomaterials during the last decades, structures and devices that do exactly that have to be developed. Graphene, the carbon wondermaterial discovered in 2004, ... -
