N. Gu et al., ELECTRICAL-PROPERTIES OF CU-TCNQ PREPARED BY THE LIMITED GROWTH, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 294, 1997, pp. 197-200
A new method, limited growth of organometallic films in liquid phase,
for preparation of Cu-TCNQ crystallites was adopted herein. Then the e
lectrical properties of the Al/Cu-TCNQ film/Cu sandwichlike structures
could be measured. The The transition between the highly resistive an
d conductive states with different parameters, such as threshold volta
ge, the shape of I-V curve, can be found depending on different averag
e sizes of Cu-TCNQ grains. The the crystal boundaries may be one of th
e important factors contributing to the switching mechanism of Cu-TCNQ
films has been suggested.
