#Controlling photoluminescence with silicon nanophotonics for better devices Silicon nanowires have a great deal of potential in future high-performance electronic sensing and energy devices.
Red photoluminescence has been reported in silicon nanowires but for many applications this hampers device performance. As Tsuyoshi Okuno from the University of Electro-Communications and his colleagues point out in a recent report
Okuno and his colleagues fabricated silicon nanowire arrays by metal-assisted chemical etching an approach that is simple and cost-effective.

into a silicon nanowire. With this new method of producing hybrid nanowires, very fast and multifunctional processing units can be accommodated on a single chip in the future.
they integrated compound semiconductor crystals made of indium arsenide (Inas) into silicon nanowires, which are suited ideally for constructing increasingly compact chips.
"In the next step, the scientists want to implement different compound semiconductors into Silicon nanowires and also optimize the size and distribution of the crystals a
One possibility is to use hybrid solar cells that combine silicon nanowires with low-cost, photoresponsive polymers. The high surface area and confined nature of nanowires allows them to trap significant amounts of light for solar cell operations.
Now, findings by Xincai Wang from the A*STAR Singapore Institute of Manufacturing Technology and co-workers from Nanyang Technological University could turn the tables on silicon nanowires by improving the manufacturing of silicon'nanoholes'arrow cavities carved into silicon wafers
Incoming light bouncing between individual silicon nanowires cannot escape the complex structure, making the material darker than dark.
and etched silicon nanowires in the areas between aluminum rings. Then they seeped a polymer between the silicon nanowire pillars.
After the plastic support solidified they etched away the silicon backing, leaving bull's-eye patterned black silicon embedded in supple plastic.

The company is also developing another thermoelectric material based on silicon nanowires that could convert a higher percentage of the energy in waste heat to electricity.
to promote the growth of silicon nanowires and to induce gold-based patterns in the silicon.
The researchers worked with both zinc oxide and silicon nanowires, and found that -when bent-the nanowires would return more than 80 percent of the way to their original shape instantaneously,

#NRL Researchers First to Detect Spin Precession in Silicon nanowires Scientists at the U s. Naval Research Laboratory (NRL) have reported the first observation of spin precession of spin currents flowing in a silicon nanowire
and the green line is the silicon nanowire transport channel. The bright dot on the end of the nanowire is used the gold nanoparticle to seed the nanowire growth.
