Polymer field effect transistors made by laser patterning

Gold nano-wires and nano-layers at laser-induced nano-ripples on PET

“…Laser-pattern is employed for the production of polymeric semiconductors and insulators on flexible polymeric substrates field effect transistors (PFETs) [10]. By defining planar nanostructures on polymer surfaces, it is possible to improve the parameters in polymer electronic memories [11].…”

Direct Fast Patterning of Conductive Polymers Using Agarose Stamping

“…Mechanical methodologies include lithography lift-off, [12] microcutting, [13] and laser ablation. [14] Subtractive chemical patterning has been demonstrated by ink-jet printing of deactivation agents, [15,16] and etching/over-oxidation after lithographic patterning with photoresist. [3,17] Ink-jet printing has the same resolution limits as in additive patterning, while the use of lithography requires expensive clean room processing.…”

Patterning ability of conducting polypyrrole thin films by positive photoresist

“…Reactive patterning techniques include photochemical patterning [1,[6][7][8], areaselected polymerization on electrodes modified with a patterned self-assembled monolayer SAM, by microcontact printing (lCP) method [7,[9][10][11][12][13][14], electro-deposition within channels between two electrodes [1,[15][16][17][18], microlithography by Scanning Electro-Chemical Microscope (SECM) [1,7,19,20], electrochemical dip-pen nanolithography (E-DPN) [1,21,22], template assisted synthesis [1,5], soft lithography assisted synthesis [23][24][25][26]. While non-reactive patterning techniques include but not limited to electronbeam writing [27] laser writing [28,29] screen printing [7,30], ink-jet printing [7,31,32], soft lithography [7,33] and nanoimprint lithography [34][35][36].…”
