Stress and doping analysis of low n-doped GaN layers on various substrates by micro-Raman mapping

Ndembi Ignoumba-Ignoumba, Camille Sonneville, Thomas Kaltsounis, Vishwajeet Maurya, Hala El Rammouz, Mohammed El Amrani, Maroun Dagher, Florian Bartoli, Thibaud Guillemin, Adrien Bidaud, Eric Frayssinet, Farid Medjdoub, Hassan Maher, Jean Marie Bluet, Dominique Planson, Julien Buckley, Yvon Cordier, Matthew Charles, Cyril Buttay

In this work, using micro-Raman spectroscopy mapping, we propose a methodology to separate the stress effect from the n-doping effect on A1LO and E2H GaN phonon modes frequency for low n-doped (<1017 cm−3) GaN layers grown on various substrates (GaN, sapphire, and silicon). This methodology…

Exploiting the insulator–metal transition of VO2 in photocatalytic methane conversion

My Nghe Tran, Duc Manh Nguyen, Matthieu Kpessu Ahounou, Ernesto de la Torre Miranda, Melissa Alzate Banguero, David Troadec, Christophe Coinon, Ahmed Addad, Karima Ben Tayeb, Alexandre Boulle, Pascale Diener, David Mele, Louis Thomas, Xavier Wallart, Lionel Aigouy, Alexandre Zimmers, Aurelian Crunteanu, Vitaly Ordomsky, Bruno Grandidier

Upon illumination, photocatalysts generate charge carriers for redox reactions, but their efficiency is often limited by carrier recombination and poor minority-carrier diffusion, despite many existing junction engineering strategies. Here we exploit the insulator–metal transition in VO2 to produce…

Is All Lithium Created Equal? Effects of Processing Conditions on Lithium Microstructure and Battery Performance

Wan-Yu Tsai, Ethan Self, Yan-Ru Lin, Till Fuchs, Kyra Owensby, Christian Lerch, Sinje Burberg, Katie Browning, Erik Herbert, Xi Chelsea Chen, Jürgen Janek, Andrew Westover

Despite growing interest in rechargeable lithium metal batteries, the influence of anode microstructure on battery performance is often overlooked, largely due to lithium’s air sensitivity and low atomic number (Z = 3), which makes it difficult to apply standard characterization methods such as…
