Bu çalışmada π bağları açısından zengin organik molekülün (Nigrosin (NIG)) optik özellikleri UV-Vis yöntemiyle belirlendi. Cam altlık üzerinde damlatma yöntemi ile büyütülen NIG ince tabakasının direkt yasak enerji değerleri; 1,42 eV (Q bandı) ve 2,94 eV (B bandı) olarak rapor edildi. Oluşturulan referans Al/p-Si ve Al/NIG/p-Si Metal/Organik aratabaka/Yarıiletken (MIS) yapılarının I-V ölçümleri sonunda tüm yapıların doğrultucu özelliğe sahip oldukları gözlemlendi. Oda sıcaklığında alınan I-V ölçümleri kullanılarak yapıların karakteristik diyot özellikleri belirlendi. Burada Al/NIG/p-Si diyotunun kapasitör özelliği, C-V ölçümleri alınarak incelendi ve yapılan hesaplamalar sonucunda bazı diyot parametreleri elde edildi. Elde edilen sonuçlar, π bağları açısından zengin olan NIG gibi organik malzemelerin elektronik sahasında kullanılabileceğini gösterdi.
