| Popis: | The electrical characteristics of organic (3,4-polyethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) contacts to HgCdTe are studied as a potential alternative to metal/HgCdTe contacts. The use of organic PEDOT:PSS contacts offers the potential for an improved contact technology for HgCdTe IR detector arrays. In this work, PEDOT:PSS contacts are deposited on n-type and p-type HgCdTe epilayers by spin coating and patterned using a metal mask. Current-voltage (I-V) characteristics are measured on these contacts, showing nearly ohmic behavior. The temperature dependence of I-V characteristics (T = 40-300 K) shows increased resistance for decreasing temperature, consistent with the temperature dependence of HgCdTe resistivity, suggesting that the I-V characteristics are primarily dominated by the HgCdTe material. |
