Weba thin AlAs capping layer can be introduced [9,10]. How-ever, the effect of this thin AlAs layer on the device performance is thus unclear and needs to be studied. In this study, we fabricated GaAs-based p-i-n junctions with a stack of 10 layers of InAs QDs as the intrinsic layer. The density of the InAs QDs in each layer was WebAfter 3 days of soaking in cell medium ( Figure 6B ), the TiO 2 thin film layer disappeared since only one peak was presented for the sample with a 200°C ALD coating. TiO 2 coated at 150°C still presented two peaks ( Figure 6B) indicating the maintenance of a TiO 2 thin film.
