Over the past two months, CEA/Leti in France, the government of Bulgaria and a consortium of universities in Poland have all made commitments and investments to a new field of research known as nanotechnology.
Actually, it is quite strange that one would call a something a “science” after simply based on its size or dimension. But when you get down to the level of 1000 or less molecules (10,000 times smaller than the thickness of human hair) that should perform a certain function, it becomes the research of very small structures, that behave differently from larger systems of the same material – hence the word nanotechnology. For example, gold looks and behaves very different when it is only a few molecules in size. For example, it melts at much lower temperatures and its color is oddly red and not that brilliant yellow that we all have come to appreciate.
Adding to the string of recent current news, next week here in Zurich we will lay the foundation stone for our new nanotechnology lab with ETH. Which begs the question, why all the buzz about nanotechnology recently? On top of all the doom and gloom in the press, why are governments, universities and corporations investing in this science?
In one word, opportunity. There are all kinds of statistics to point to, such as the analysts of Credit Suisse who estimate the growth rate for nanotechnology to be 25 to 30% per year with a market size of $220 billion by 2010. Or Lux Research, who say that nanotechnology will impact $2.9 trillion worth of products across the value chain by 2014. If you will, stats are just predictions, and as an engineer I prefer hard facts.
When I think about the future promise of nanotechnology I don’t need charts to see the opportunity, working at a Lab I can see it first hand. While nanotechnology is already making its way into common products from lipstick to the paint on a car, here in Zurich we are taking it further, much further: for example, we work on atomic switches, where single electrons decide over whether the switch is open or closed. These projects are important for the future of our industry, that will soon face the challenge, that Moore’s law of doubling the number of transistors every 18 months on a conventional CMOS chip no longer can be maintained.
