do u know how is nano applied in mobile phones?tell me,which part of a mobiel phone is nano . or something like that,the more details the better it is!thanks ya
Nanoscience is the study of phenomena and manipulation of material at the nanoscale, in essence an extension of existing sciences into the nanoscale. The sizes of the mobile phones we use today can be reduced drastically by this science. It is an upcoming science and will take some time to develop. but the sizes can be reduced to such an extent that a wire and a phone will look similar when seen together.
Nanotechnology has to do with assembling things on the molecular level. I doubt if cell phones are technological.
In cell phones or wireless communications in general, Silicon-Germanium (SiGe) materials are used. Applying a 50nm layer of SI on Ge, through an epitaxy growth method, is referred to as a strained layer growth since the lattice constant of the Si and Ge are different. This type of growth is only applicable to very thin growth layers. The strained layer allows electrons to flow more quickly through the material creating a faster device.
nanotechnology includes the latest electronic chips Your mobile phone has to communicate at frequencies of about 1GHz, and does numerical computations at the speed of a few GHz too For that, you need the latest technologies, including the 90nanometer chips. (well, you don't NEED it, but it allows you to do the job better) 90nanometers refers to the smallest part of the smallest component on the chip. (usually the minimal width of the grid of transistors) now, in a cell phone, you also have a lcd screen that is sometimes considered nanotechnology, and also 1Mpixel (or more) photocaptors (ie: the camera on your cellphone). And that's nanotechnology too. In all that, you don't have a single moving object, but the electronic chips have nanometric properties. ie: there is nanotechnology, but no MEMS(micro electro-mechanical systems) since nothing is mechanical (ie: moves) in there. Another thing that can be considered nanotechnology is the battery. Bateries are only as powerful as the surface of metal there is inside, so to boost the surface while keeping the same volume and mass, they create nanometric bumps on the surface, that will boost the surface of metal, and power of the batery a bit. (a lot)
