Avoiding avalanche breakdown in planar GaN Gunn diodes by means of a substrate contact

S García-Sánchez, S Pérez, I Íñiguez-De-La-Torre, B García-Vasallo, L Huo, R Lingaparthi, D Nethaji, K Radhakrishnan, M Abou Daher, M Lesecq, T González, J Mateos, M. Abou Daher

Abstract Impact ionization originated by the buffer leakage current, together with high electric fields ( > 3 MV cm −1 ) at the anode corner of the isolating trenches, has been identified as the failure mechanism of shaped planar GaN Gunn diodes when biased above 20 V, so that no evidence of...

Selective area epitaxy of in-plane HgTe nanostructures on CdTe(001) substrate

N Chaize, X Baudry, P-H Jouneau, E Gautier, J-L Rouvière, Y Deblock, J Xu, M Berthe, C Barbot, B Grandidier, L Desplanque, H Sellier, P Ballet

Semiconductor nanowires (NWs) are believed to play a crucial role for future applications in electronics, spintronics and quantum technologies. A potential candidate is HgTe but its sensitivity to nanofabrication processes restrain its development. A way to circumvent this obstacle is the selective...

Biomimetic anti-icing surfaces applied to second generation refrigerating systems

Bas Florian, Maude Jimenez, Yannick Coffinier, Vincent Thomy, Anthony Delahaye, L. Fournaison, Pascal Clain

One action to protect environment in this global climate change crisis is to lower the use of CFCs (ChloroFluoroCarbons) in primary refrigerating systems. To reduce the use of such substances, second generation refrigerating systems using ecological high energy density refrigerant (ice slurry) have...

Cooperative dynamics of PARP-1 zinc-finger domains in the detection of DNA single-strand breaks

Parvathy A Sarma, Corinne Abbadie, Fabrizio Cleri

The DNA single-strand break (SSB) repair pathway is initiated by the multifunctional enzyme PARP-1, which recognizes the broken DNA ends by its two zinc-finger domains, Zn1 and Zn2. Despite a number of experiments performed with different DNA configurations and reduced fragments of PARP-1, many...
