However, for hydrogenated amorphous silicon (a-Si:H) precursor layers containing about 10 at.% hydrogen, hydrogen needs to be removed prior to liquid phase crystallization to avoid bubble formation and peeling. For this purpose, an at least 12 hours annealing procedure up to 550°C is considered necessary thus involving long process time and high costs. In this article, we investigate the use of thick hot wire grown a-Si:H films which turn out to need considerably less time for dehydrogenation than dense plasma-grown a-Si:H. The dehydrogenation process is studied by depth profiles of hydrogen concentration and medium range order (MRO) using Raman spectroscopy analysis at etch pits. The results show already at an annealing temperature of 450°C the disappearance of all detectable H in the substrate-near part and the complete removal of H at 550°C after about 4 hours annealing. We attribute this rather fast hydrogen removal to the formation of interconnected voids primarily in the substrate-near range. In the same range of the film, we find a correlation between hydrogen concentration and medium range order suggesting that a silicon network reconstruction due to hydrogen out-diffusion causes an observed decrease of reciprocal MRO. The results stress the importance of void-related microstructure in the a-Si:H for hydrogen removal at a rather low annealing temperature and short annealing time. Our results suggest that hot wire a-Si:H films which can be grown with a high deposition rate and a rather pronounced void-related microstructure may be well suited as economic precursor layers. 000889309 536__ $$0G:(DE-HGF)POF3-113$$a113 - Methods and Concepts for Material Development (POF3-113)$$cPOF3-113$$fPOF III$$x0 000889309 588__ $$aDataset connected to CrossRef 000889309 7001_ $$0P:(DE-Juel1)171617$$aWang, Weiyan$$b1 000889309 7001_ $$0P:(DE-HGF)0$$aNickich, V.$$b2 000889309 7001_ $$0P:(DE-Juel1)130283$$aPennartz, F.$$b3$$ufzj 000889309 7001_ $$0P:(DE-Juel1)130246$$aHaas, Stefan$$b4 000889309 7001_ $$0P:(DE-Juel1)130277$$aNuys, M.$$b5$$ufzj 000889309 7001_ $$0P:(DE-Juel1)130217$$aBeyer, W.$$b6$$ufzj 000889309 773__ $$0PERI:(DE-600)1482896-0$$a10.1016/j.tsf.2020.138353$$gVol. 714, p. 138353 -$$p138353 -$$tThin solid films$$v714$$x0040-6090$$y2020 000889309 8564_ $$uhttps://juser.fz-juelich.de/record/889309/files/Postprint.pdf$$yPublished on 2020-09-18.
