Two kinds of heterojunction diodes of porous silicon (PS) with soluble polyaniline (PANI) werefabricated. One is a heterojunction diode of PS with water-soluble copolymer of polyaniline (PAOABSA)
Al/PS-PAOABSA/Au cell as rectifying diode. Another is a heterojunction diode of PS with solublepolyaniline doped with DBSA
Al/PS-PANI (DBSA)/Au cell as light emitting diode (LED). The rectifyingcharacteristics of the rectifying diodes were measured as a function of the degree of sulfonation and thickness of the copolymers
as well as oxidation of PS.The rectifying ratio of the heterojunction can reach 5.0×104 at ± 3 V bias.For the LED
the photoluminescence(PL) and electroluminescence(EL) spectra were measured and discussed.
