The development of new types of electronic devices based on conductive polymers requires precise and controlled deposition of these materials in thin layers. This book examines the latest results in research of deposition of polypyrrole (PPY) thin films by advanced method - Matrix Assisted Pulsed Laser Evaporation (MAPLE). It also provides a brief survey of the laser deposition of conductive polymers, theoretical analysis of the mechanisms of deposition by MAPLE method, definition of both source-PPY properties and deposition conditions necessary for successful thin layer fabrication.
