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…

Boltzmann to Lindblad: classical and quantum approaches to out-of-equilibrium statistical mechanics

Stefano Giordano, Giuseppe Florio, Giuseppe Puglisi, Fabrizio Cleri, Ralf Blossey

Open quantum systems play a central role in current nanoscale technologies, such as molecular electronics, quantum heat engines, quantum computation and information processing. A major theoretical challenge is to construct dynamical models that are simultaneously consistent with classical…

AlGaN Back-Barrier Integration for Trap Reduction in Buffer-Free GaN HEMTs on SiC

François Grandpierron, Elodie Carneiro, Lyes Ben-Hammou, Anders Lundskog, Jui-Che Chang, Jr-Tai Chen, Farid Medjdoub

This work investigates the impact of incorporating an AlGaN back barrier (BB) in buffer-free AlGaN/GaN high electron mobility transistors (HEMTs) on SiC. Both devices use an AlN nucleation layer (NL) for vertical isolation, while the modified structure introduces an Al0.2Ga0.8N BB beneath the GaN…

Coherent electronic transport in HgTe nanostructures grown by selective area epitaxy

Nicolas Chaize, Xavier Baudry, Yves Deblock, Maxime Berthe, Bruno Grandidier, Ludovic Desplanque, Philippe Ballet, Hermann Sellier

This paper reports on the quantum coherent properties of in-plane HgTe nanodevices obtained by selective area growth (SAG) on CdTe substrates using a silicon dioxide mask. Low-temperature magneto-transport measurements were performed on devices with a ring geometry to extract the phase coherence…
