Sažetak
Inorganic semiconductor materials have for a long time been a standard member of electronic devices ecosystem, with silicon being the material of choice for most applications. Lately, organic semiconductors have become more visible not only for scientists but also to general public, with applications such as OLED screens and organic photovoltaic devices becoming a part of our daily lives. Introducing nanostructuring in both types of materials has proven to be advantageous for their properties and applications. Heterojunction interfaces between organic and inorganic thin films in devices show promise in using the advantages of both materials simultaneously. We present our work on devices based on heterojunctions of porous silicon formed by anodisation in HF- based electrolytes and organic thin films formed by vacuum evaporation. For the inorganic part of the heterojuction we choose porous silicon due to its compatibility to established CMOS technology and its enormous surface area being presented to thin organic films. For organic part of the junction we investigated the applicability of various organic semiconductor thin films for optoelectronic and biosensing applications. Our porous silicon- based devices show enhancement in optical response in comparison to devices based on bulk silicon.
