Synthesis of 2-dimensional Materials for Applications in Electronics

Two-dimensional materials such as transition metal dichalcogenides (TMDs) are intensively investigated because of their unique properties, such as thickness depend band gaps and all surface nature. These properties give rise to new physics and chemistry and have potential for emerging applications. So far mainly group six (Mo/W) TMDs have been investigated, while very little is known about group 10 (Pt/Pd) TMDs. In particular, PtSe2 has drawn attention due to a transition fromsynthesis of PtSe2 by thermally assisted conversion (TAC) of Pt films is outlined. The composition and morphology is shown by several characterization techniques including Raman spectroscopy, X-ray photoelectron spectroscopy, TOF-SIMS and transmission electron microscopy. As large-scale films and pre-pattered structures can be grown the methodology, TAC allows to fabricate electronic devices using standard micro-fabrication technology.This is of particular importance as the synthesis temperature for PtSe2 can be below 450°C, allowing (BEOL) integration with silicon devices. Examples for high performance chemical sensors, IR-photodetectors and MEMS devices with PtSe2 will be presented.
