(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Fermi level controlled point defect balance is demonstrated in ion irradiated indium oxide (In2O3). Specifically, our observations can be sub-divided into the formation of isolated Frenkel pairs and secondary defects, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Nitrogen in group-IV semiconductors has become a well-established element of qubits capable of room-temperature operation. In silicon carbide, nitrogen can occupy different nonequivalent lattice sites, giving rise to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)With the continuous scaling of the CMOS technology, the CMOS circuits are considered to be more tolerant to Single event Latchup (SEL) effects due to the reduction in the supply voltages. This paper reports the results ...
-
(Journal article / PublishedVersion; Peer reviewed, 2020)This is the first direct observation that surface proton hopping occurs on SrZrO3 perovskite even under a H2 (i.e. dry) atmosphere. Understanding proton conduction mechanisms on ceramic surfaces under a H2 atmosphere is ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We report new LA-ICP-MS U-Pb zircon ages of varied crystalline rocks occurring in the Serre Chevalier crystalline terrain, an allochtonous basement unit located at the top of the Briançonnais nappes stack ∼5 km west of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We use first-principle calculations based on hybrid functional and the Bethe-Salpeter equation method to investigate the electronic and optical properties of dichalcogenide TlGaTe2. Based on theoretical studies, TlGaTe2 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Defect segregation at homo- and heterointerfaces enables heterogeneous doping of functional nanocomposites for enhanced charge and mass transport or storage properties compared to homogeneously doped bulk materials. The ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Point defects in solids are promising single-photon sources with application in quantum sensing, computing and communication. Herein, we describe a theoretical framework for studying electric field effects on defect-related ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In recent years, the scientific community has shown an increasing interest in regards to the investigation of novel materials for the intercalation of lithium atoms, suitable for application as cathodes in the new generations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Sustainable Commercial Fishing is the second challenge at the Nordic AI Meet following the successful MedAI, which had a focus on medical image segmentation and transparency in machine learning (ML)-based systems. FishAI ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We study the active flow around isolated defects and the self-propulsion velocity of +1/2 defects in an active nematic film with both viscous dissipation (with viscosity η) and frictional damping Γ with a substrate. The ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract. The microstructural record of fault rocks active at the brittle–ductile transition zone (BDTZ) may retain information on the rheological parameters driving the switch in deformation mode and on the role of stress ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The dynamic evolution of fault zones at the seismogenic brittle–ductile transition zone (BDTZ) expresses the delicate interplay between numerous physical and chemical processes. Deformation and fluid flow at the BDTZ are ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)With the demand of aggressive scaling in nanoelectronics, further progress can be realized by integration of high mobility semiconductors, such as III–V compound semiconductors, with complementary metal‐oxide‐semiconductor ...
