France has a strong academic tradition and is committed to investing in research and education. Here's what French academics make.
Solid state physics, surfaces and interfaces
Among the most promising materials for “More than Moore” technologies (chemical sensors, photodetectors, nano-batteries,…), 2D transition metal dichalcogenides have recently been identified as high-potential candidates. In particular, semiconducting transition metal disulfides such as MoS2 and WS2 have been thoroughly studied because of their chemical robustness, but their synthesis actually requires ultrahigh-temperature processes (> 800°C) which severely hinder their integration capabilities.In this context, tin disulfide (SnS2) appears as a good alternative to MoS2 or WS2 since it can be obtained with good crystallinity at much lower temperatures (< 350°C), making it potentially compatible with an ”above IC” integration. Moreover, tin is a relatively non-toxic and earth-abundant metal with almost all of its oxide and sulfide derivatives (SnS, Sn2S3, SnS2, SnO et SnO2) being semiconductors, which opens up a wide range of perspectives in term of potential applications.This PhD work will aim at developing industrially-relevant processes for the synthesis of SnS2 (or other semiconducting 2D materials that can be obtained at low temperature), either by sulfurization of the corresponding oxide or using a deposition process such as ALD (Atomic Layer Deposition), in order to create novel devices based on these materials, and ideally compatible with already-existing technologies on 200 or 300 mm wafers. This study will also cover the characterization of the obtained materials through different methods (XPS, X-ray fluorescence, Raman, XRD, TEM, KPEEM,..) as well as the assembly of basic devices allowing to establish a correlation between physicochemical properties and electrical characteristics of the target material.
