• It was found that the various types of conductivity cells of aromatic hydrocarbons possess great discrepancies of their electrical resistivity. The resistivity observed with the sandwich-type cell, perylene; 10<SUP>18∼19</SUP> Ωcm., coronene; 10<SUP>17∼18</SUP> Ωcm., and violanthrene; 10<SUP>14</SUP> Ωcm., is in quite good agreement with that of the bulk specimen. However, a great difference was found between the resistivities of the sandwich-type and the surface-type cells, perylene; 10<SUP>13</SUP> Ωcm., coronene; 10<SUP>12∼13</SUP> Ωcm., and violanthrene ; 10<SUP>9</SUP> Ωcm. This discrepancy in resistivity can be assumed to be introduced from the textured structure of the evaporated films and the substantial anisotropy of crystals; the crystals are in alignment with their a·b plane with the film surface. This orientation was found from the X-ray diffraction results, combined with the electron microscopic observation and the electron microdiffraction results.
