A Conductivity Modulated Polysilicon Thin-Film Transistor
This paper reports a novel high voltage Conductivity Modulated Thin-Film Transistor (CMTFT) fabricated using polycrystalline silicon. The transistor uses the idea of conductivity modulation in the offset region to obtain a significant reduction in on-state resistance. Experimental on-state and off-state current-voltage characteristics of the CMTFT have been compared with those of the conventional offset drain device. Results show that the CMTFT has six times to more than three orders of magnitude higher on-state current handling capability for operating at drain voltages ranging from 15 V to 5 V while still maintaining low leakage current and providing even faster switching speed. The CMTFT devices can be fabricated using a low temperature process (620/spl deg/C) which is highly desirable for large area electronic applications.<<ETX>>
A high-voltage polysilicon TFT with multigate structures
An approach is proposed for obtaining a high-voltage thin-film transistor (TFT) with multigate structure where polysilicon TFTs are connected in series. A basic principle for high-voltage operation has been investigated in detail through calculations based on a model describing log I/sub DS/-V/sub GS/ characteristics observed in a single-gate polysilicon TFT. It has been found that off-state (V/sub GS/ >
The German centenary of the First World War
In the run up to the 2014 centenary of the First World War, the German public was gripped by a heated debate on the origins of the war. This article explores the nature of this controversy and its role in shaping national commemoration of the Great War. It also draws parallels between the commemorations of the fiftieth anniversary of the outbreak of the war in 1964 and those of 2014. Through a comparison of Germany’s national memories of the war with those in Britain and France, the article also reveals how different and sometimes conflicting national interpretations of the history of the First World War have affected centenary commemoration. Memories of the First World War are nation-specific, constructed and developed over time to suit a particular view of a country’s past. Moreover, they can be instrumental in influencing that country’s future development and relations with its neighbours.
