We present a simple method for fabricating superhydrophobic silicon surfaces. The method
consists of irradiating silicon wafers with femtosecond laser pulses and then coating the …

We compare the optical properties, chemical composition, and crystallinity of silicon microstructures
formed in the presence of SF 6 by femtosecond laser irradiation and by nanosecond …

Photodetectors fabricated on microstructured silicon are reported. The photodetectors exhibited
high photoresponse; at 3 V bias, the responsivities were 92 A/W at 850 nm and 119 A/W …

We investigated the current–voltage characteristics and responsivity of photodiodes
fabricated with silicon that was microstructured by use of femtosecond-laser pulses in a sulfur-…

We fabricate submicrometer silicon spikes by irradiating a silicon surface that is submerged
in water with 400 nm, 100 fs laser pulses. These spikes are less than a micrometer tall and …

MATERIALS AND METHODS Patients. One or more tumors that were histologically typical
of pheochnomocytoma had been removed from each patient; de-differentiation of histology …

In this article, we present summaries of the evolution of surface morphology resulting from
the irradiation of single-crystal silicon with femtosecond laser pulses. In the first section, we …

We report on the formation of high-density regular arrays of nanometer-scale rods using
femtosecond laser irradiation of a silicon surface immersed in water. The resulting surface …

We irradiated silicon with a train of femtosecond pulses in the presence of SF 6 , H 2 S, H 2 ,
SiH 4 , and a mixture of Ar and SF 6 in order to analyze the role of the background gas in …

Loss of cholinergic transmission in the cortex and hippocampus is a characteristic feature of
Alzheimer's disease, and visualization of functional cholinergic synapses in the brain with …
