Abstract

Jedna od glavnih tema istraživanja u modernoj senzorici obuhvaća funkcionalizaciju nanostrukturiranih materijala u svrhu poboljšanja osjetljivosti i selektivnosti senzora. Eksperimentalni put prema unapređenju senzora uključuje izradu i karakterizaciju materijala velike specifične površine, njihovo tretiranje fizikalnim i kemijskim metodama, te ispitivanje njihovog odziva na pokusne agense. Doktorski rad će biti baziran na izradi nanostrukturiranog silicija, s naglaskom na porozni silicij dobiven elektrokemijskim jetkanjem. Fokus ovog rada je ispitati njegova senzorska svojstva, primarno spram para organskih otapala i plinova, te utjecaj funkcionalizacije kisikom na odziv takvog senzora.

Abstract (english)

One of the main research topics in modern sensorics includes functionalisation of nanostructured materials with a goal of improving sensors’ sensitivity and selectivity. The experimental path leading to such improvement involves production and characterisation of materials with a large specific surface area, their physical and chemical treatment, and assessment of their response to test chemicals. The work of this thesis will be based on production of nanostructured silicon, with emphasis on porous silicon obtained by electrochemical etching. Focus of the thesis will be to explore the sensing properties of nanostructured silicon, primarily with respect to organic vapours and gases. Also, the effects of functionalisation and morphological characteristics on the sensor’s response will be studied.
