Abstract
A method is disclosed for producing an electron emitter () with a component surface () of which is coated with a coating () that contains nanorods (), in particular carbon nanotubes. According to said method, an elastomer film is applied and is then peeled off to obtain a surface from which carbon nanotubes () with an upright orientation project upward from an inorganic and electrically conductive adhesive layer (). In another example, an overall coating region of the electron emitter () has an average number (n) of carbon nanotubes () with a predominantly upright orientation that project upward from the electrically conductive adhesive layer (), the number of nanotubes () with a predominantly upright orientation per mmprotruding from the adhesive layer deviating from the average value (n) by not more than 25% for each partial coating region of a size of at least 10mm.
