Quartz SAW filters
03 February, 2005Epcos is releasing its quartz SAW components for radio remote control in the QCC8B package with a footprint of 3.8 x 3.8 mm.
Cations perform a quick change
27 January, 2005Researchers with the US Department of Energy's Lawrence Berkeley National Laboratory (Berkely Lab) and the University of California at Berkeley have shown that for nanocrystals, the doping process in which one type of positively charged atom, or cation, is exchanged for another, takes place at a much faster rate than for crystals of extended size and is fully reversible, something that is virtually forbidden in micro-sized crystals under the same environmental conditions.
Crystal-based ASK transmitter
06 July, 2004Maxim has introduced the MAX7044, claimed to be the world's smallest VHF/UHF, PLL-based, ASK transmitter with +13 dBm output power packaged in a 3 x 3 mm, 8 pin SOT23.
Why silicon crystals lose their 'edge'
05 November, 2003Physicists have discovered a mechanism that forces sharp edges on the surface of a silicon crystal to become rounded, and have described this rounding in detail for the first time
Crystal growth yields more precise semiconductors
28 November, 2001Traditionally, scientists grow quantities of single-crystalline semiconducting materials by immersing the tip of a pencil-shaped starter crystal in a melt of the same composition.
7.7 Inch Low-Temperature Polysilicon LCD
17 November, 2000Toshiba Corporation has announced commercialisation of a 7.7 inch, low-temperature, polysilicon thin film transistor (TFT) liquid crystal display (LCD), designed for mid-size electronic books supporting Microsoft's ClearType technology. Jointly developed by Microsoft and Toshiba the display will enter mass production at the beginning of 2001.
