A sensitive photodiode photometer for laboratory experiments

Interface engineering of a highly sensitive solution processed organic photodiode.

We report on tuning of the interfacial properties of a highly sensitive organic photodiode by introducing a buffer layer between the anode and the semiconductor layer. The effects of different buffer layers consisting of a self-assembled monolayer (SAM), PEDOT:PSS, and pentacene on the morphology and crystallinity of the upper-deposited bulk heterojunction semiconductor layer are carefully anal...

Thermal-Blooming Laboratory Experiments

• We conducted a multiphase series of laboratory experiments to explore the adaptive optics compensation of a laser beam distorted by strong thermal blooming. Our experimental approach was to create on a small, low-power beam the same phase distortion that would be experienced by a large, high-power beam propagating through the atmosphere and to apply phase compensation via deformable mirrors. ...

Time-Sensitive Network Experiments

Time-sensitive network experiments are difficult. There are major challenges in generating realistic traffic with highly accurate packet arrivals, and monitoring various system performance metrics which require high precision in timing is not trivial. Parts of these problems arise from the fact that generic network software and hardware components do not provide high-precision timing guarantees...

Laboratory experiments simulating a coastal river inflow

The dynamics of buoyant water entering a rotating basin are studied using a series of laboratory experiments designed to elucidate the alongshore transport mechanisms in river plumes. Inflowing water, which is discharged perpendicular to the tank wall, is observed to form a growing anticyclonic bulge and a coastal current downstream of the bulge. Detailed simultaneous measurements of the veloci...
