  • Doping organic semiconductors
    Patent number: 10559753
    Abstract: We describe a method for reducing a parasitic resistance at an interface between a conducting electrode region and an organic semiconductor in a thin film transistor, the method comprising: providing a solution comprising a dopant for doping said semiconductor, and depositing said solution onto said semiconductor and/or said conducting electrode region to selectively dope said semiconductor adjacent said interface between said conducting electrode region and said semiconductor, wherein depositing said solution comprises inkjet-printing said solution.
    Type: Grant
