•  3C(a–c)). As can be observed from Figure 3D(a–c), the enhanced bandgap values for CISe, CIGSe and CZTSe are 1.26 eV, 1.18 eV and 1.15 eV, respectively. During prolonged light exposure there might occur a reorientation and reformation of bonds depending on the stability of the nanocrystals. Thus

• , so that we do not expect qualitative differences in the fast reorientation dynamics that accompany the proton discharge step [17]. Thus the overall effect of the presence of the hydrogen layer on the Volmer discharge step should not be large and is furthermore expected to be similar for all studied

• in the second or in the third layer immediately before the reaction. This supports earlier conclusions that the reaction mechanism at high driving force (i.e., at high surface charge densities) does not require a (fluctuative) reorientation of water molecules in the first layer to take place. Rather

• that the crystallites start to orient along the same axis and that an increase in orientation with time occurs. Furthermore, a change in the zone axis and therefore top/bottom crystal face from [112] to [111] occurs after 2 days which indicates that a reorientation process takes place. In addition, the

Such crystallographic reorientation within mesocrystals has been suggested previously [3][8][9][11]. Formation of secondary nanoparticles Mesocrystals have a large amount of energetically

EELS and electron diffraction experiments show that a reorientation of the primary building blocks as well as several phase transformations occur prior to the formation of the secondary nanoparticles. However, the

MSPS can have two conformations, namely the agraffe

This may enable the obtainment of samples with controlled, uniform interfaces and crystallographic orientations even in a random deposition process. However, such a reorientation
