Semiconductor-oxide Nanocomposites Based on Porous Semiconductors
Rare-earth containing oxide nanocomposites are prepared of porous GaP and GaAs templates in a controlled fashion. The initial porous GaP and GaAs networks are replaced by GaPO4 and Ga2O3 structures, respectively, during annealing at temperatures from 500 to 900 C. The impregnation of Eu and Er lanthanides from EuCl3:C2H5OH and ErCl3:C2H5OH solutions results in the formation of lanthanide contai...
متن کاملHybrid organic-inorganic porous semiconductor transducer for multi-parameters sensing.
Porous silicon (PSi) non-symmetric multi-layers are modified by organic molecular beam deposition of an organic semiconductor, namely the N,N'-1H,1H-perfluorobutyldicyanoperylene-carboxydi-imide (PDIF-CN2). Joule evaporation of PDIF-CN2 into the PSi sponge-like matrix not only improves but also adds transducing skills, making this solid-state device a dual signal sensor for chemical monitoring....
متن کاملQuantum dot-doped porous silicon metal–semiconductor metal photodetector
In this paper, we report on the enhancement of spectral photoresponsivity of porous silicon metal-semiconductor metal (PS-MSM) photodetector embedded with colloidal quantum dots (QDs) inside the pore layer. The detection efficiency of QDs/PS hybrid-MSM photodetector was enhanced by five times larger than that of the undoped PS-MSM photodetector. The bandgap alignment between PS (approximately 1...
متن کاملVolatile Organic Compounds Monitoring for Semiconductor Foundry Clean Room Air
Air samples were collected in consecutive days using Summa canisters from semiconductor foundry clean rooms and air entrances. By coupling a NuTech preconcentrator with an Agilent GC-MS, an optimized method for qualitative and quantitative analysis of VOC compounds was developed. Method detection limit (MDL), blank spike (BS) and blank spike duplicate (BSD), etc. were estimated for method valid...
متن کاملCoherent and ultrafast optoelectronics in III-V semiconductor compounds
III–V compound semiconductors offer a fascinating multitude of phenomena which have become accessible via ultrafast time-resolved spectroscopy. Coherent vibronic and electronic dynamics are prepared by excitation with taylored femtosecond laser pulses. The analysis of their temporal dephasing or decay provides deep insights into the interaction between electronic and vibronic degrees of freedem...
