Effects of InAlN underlayer on deep traps detected in near-UV InGaN/GaN single quantum well light-emitting diodes

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Mauro Mosca, Camille Haller

Two types of near-UV light-emitting diodes (LEDs) with an InGaN/GaN single quantum well (QW) differing only in the presence or absence of an underlayer (UL) consisting of an InAlN/GaN superlattice (SL) were examined. The InAlN-based ULs were previously sho ...

Photocapacitance spectroscopy of InAlN nearly lattice-matched to GaN

Nicolas Grandjean, Jean-François Carlin, Marcel Py, Lorenzo Lugani

We study the deep levels in InAlN nearly lattice-matched to GaN by photocapacitance spectroscopy. This technique allows the study of very deep levels having too slow thermal emission rates to be detected by other deep level spectroscopy techniques. We will ...

Capacitance behavior of InAlN Schottky diodes in presence of large concentrations of shallow and deep states related to oxygen

Nicolas Grandjean, Jean-François Carlin, Marcel Py, Lorenzo Lugani

The capacitance-voltage-temperature characteristics of nonintentionally doped In0.16Al0.84 N/n+- GaN Schottky diodes were measured at 1 MHz and in the 90–400 K range. They are discussed in the framework of existing theories, which properly treat the Poiss ...

Effect of inclined jet screen on turbidity current

Anton Schleiss, Giovanni De Cesare, Christoph Oehy

The sustainable use of reservoirs for irrigation, flood protection, water supply and hydropower may be endangered due to unavoidable reservoir sedimentation. Turbidity currents are the main process for the transport and deposit of sediments in reservoirs, ...

Cold intrusions in Lake Baikal: Direct observational evidence for deep-water renewal

Alfred Johny Wüest

We studied cold, deep-water intrusions in the South Basin of Lake Baikal on the basis of 2 yr of data (December 1995-November 1997) from near-bottom and near-surface thermistor strings, monthly conductivity-temperature-depth (CTD) profiles, and a near-bott ...
