   Sammanfattning : The conventional 2D geometrical scaling of transistors is now facing many challenges in order to continue the performance enhancement while decreasing power consumption. The decrease in the device power consumption is related to the scaling of the power supply voltage (Vdd) and interconnects wiring length. LÄS MER

   Sammanfattning : High speed analog-to-digital converters (ADCs) used in, e.g., read channel and ultra wideband (UWB) applications are often based on a flash topology. The read channel applications is the intended application of this work, where a part of the work covers the design of two different types of 6-bit flash ADCs. LÄS MER

   Sammanfattning : More and more electronic products, like battery chargers and power supplies, as well as applications in telecommunications and automotive electronics are based on System-on-Chip solutions, where signal processing and power devices are integrated on the same chip. The integration of different functional units offers many advantages in terms of reliability, reduced power consumption, weight and space reduction, leading to products with better performance at a hopefully lower price.

7. 20. STM studies of overlayers on semiconductor or insulator surfaces

   Författare :Thorbjörn Jemander; Struan Gray; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Scanning tunneling microscopy (STM) operated in ultra-high vacuum (UHV) has been used to study overlayers on semiconductor or insulator surfaces. The overlayers have been deposited by magnetron sputtering, thermal evaporation or by gas exposure, and the investigated material systems include Mo on MgO, Ni on SiC, Sn on Si(lll), C on Si(lO0) and O on Si(lll).
