Low p-type contact resistance by field-emission tunneling in highly Mg-doped GaN

Nicolas Grandjean, Denis Martin, Hironori Okumura

Mg-doped GaN with a net acceptor concentration (NA-ND) in the high 10 19 cm(-3) range was grown using ammonia molecular-beam epitaxy. Electrical properties of NiO contact on this heavily doped p-type GaN were investigated. A potential-barrier height of 0.2 ...

Band-to-band tunneling distance analysis in the heterogate electron-hole bilayer tunnel field-effect transistor

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre

In this work, we analyze the behavior of the band-to-band tunneling distance between electron and hole subbands resulting from field-induced quantum confinement in the heterogate electron-hole bilayer tunnel field-effect transistor. We show that, analogous ...

Multiple polariton modes originating from the coupling of quantum wells in planar microcavity

Benoît Marie Joseph Deveaud, Daniel Oberli, Fauzia Jabeen, Claudéric Ouellet-Plamondon, Grégory Chilpéric Sallen

We report on the observation of multiple polariton modes, originating from an electronic coupling between quantum wells inside a planar microcavity. A series of excitonic transitions are measured for a bare quantum well stack and are precisely identified t ...

Assessment of phase-field-crystal concepts using long-time molecular dynamics

William Curtin, Kristopher Learion Baker

The ability of the phase-field-crystal (PFC) model to quantitatively predict atomistic defect structures in crystalline solids is addressed. First, general aspects of the PFC model are discussed within the context of obtaining quantitative results in solid ...

Lyapunov exponents of random walks in small random potential: the upper bound

Thomas Mountford, Jean-Christophe Mourrat

We consider the simple random walk on Z(d) evolving in a random i.i.d. potential taking values in [0, +infinity). The potential is not assumed integrable, and can be rescaled by a multiplicative factor lambda > 0. Completing the work started in a companion ...

Non-Rigid Graph Registration using Active Testing Search

Pascal Fua, Raphael Sznitman, Jan Kybic, Miguel Amável Dos Santos Pinheiro

We present a new approach for matching sets of branching curvilinear structures that form graphs embedded in R2 or R3 and may be subject to deformations. Unlike earlier methods, ours does not rely on local appearance similarity nor does require a good init ...

Monte Carlo modeling of crystal channeling at high energies

Alessio Ferrari, Philippe Jean Schoofs, Francesco Cerutti

Channeling in bent crystals is becoming a reliable and efficient technique for collimating beams. At CERN, the installation of crystals in LHC is under scrutiny by the UA9 collaboration with the goal of investigating if they are a viable option for the col ...

Experimental Analysis of Lag Sources in Pinned Photodiodes

Maher Kayal, Nicolas Blanc, Lysandre-Edouard Bonjour

A measurement method is reported to distinguish the different mechanisms that lead to image lag in image sensors based on pinned photodiodes (PPDs). This new method can differentiate between the lag caused by a potential barrier or pocket and gate traps in ...
