It covers the latest developments in field emission theory as well as new methods towards improving thermionic and cold cathodes. It addresses thermionic cathodes, such as oxide cathodes, impregnated and scandate cathodes, as well as photocathodes and field emitters ? the latter comprising carbon nanotubes, graphene and Spindt-type emitter arrays. Despite the rise and fall of the once dominant types of vacuum tubes, such as radio valves and cathode ray tubes, cathodes are continually being improved upon as new applications with increased demands arise, for example in electron beam lithography, high-power and high-frequency microwave tubes, terahertz imaging and electron sources for accelerators. Written by 17 experts in the field, the book presents the latest developments in cathodes needed for these applications, discussing the state of the art and addressing future trends. 410 0$aTopics in applied physics ;$vVolume 135. 606 $aVacuum microelectronics 606 $aField emission 615 0$aVacuum microelectronics. 615 0$aField emission. 676 $a621.381 702 $aGaertner$b Georg 702 $aKnapp$b Walter H. 702 $aForbes$b R$g(Richard), 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996418436003316 996 $aModern Developments in Vacuum Electron Sources$91882009 997 $aUNISA
