A Lund University professor has formulated a new process for semiconductor fabrication that utilizes gold nanoparticles rather than the traditional silicon substrate. This new process employs gas deposition and suspends gold nanoparticles in the gas flow, causing nanoscopic semiconductor structures to grow on the gold nanoparticles. Following this, the finished structures float into an oven for curing.
At present, only regular conductive nanowires are grown but scientists hope to examine this process in a deeper manner to develop unique nanowires that serve as p-n diodes.
Recently, Lund University scientists measured the Hall Effect in nanowires. This major breakthrough can be used to tweak the electronic properties of nanowires, and also help in producing a new range of nanowire-based devices.
In another discovery, scientists from the Chalmers University of Technology created a nanoplasmonic sensor platform that can be used to sense low-abundance biomolecules in small sample volumes. This newly created nanoplasmonic sensor platform will help in conveying analyte to the sensor surface.
By combining nanosensors into nanochannels, the analyte is transported to all the sensor’s sensitive parts, thereby enhancing time response, and capture efficiency of this new nanoplasmonic sensor platform in contrast to conventional sensor systems.
These latest developments reveal that Swedish scientists are making important breakthroughs in the field of nanotechnology. They also demonstrate the diversity in the field.
Sweden also has many companies working on nanotechnology. When one looks at the Swedish population and compares this to the nanotech activity, it becomes obvious that on a per capita basis, it is highly active and undoubtedly making significant advances towards becoming a knowledge-based economy.
