In the PCL/PVPh blend, dendritic crystals with truncated lozenge morphology were observed, whereas the PCL/PVC blend exhibited seaweed-like crystals characterized by approximately six curved branches. Electron diffraction patterns demonstrate that in both blend systems the PCL chain stems are oriented perpendicularly to the film surface, with the <i>a</i>- and <i>b</i>-axes aligned parallel to the film plane. However, the PCL/PVPh blend exhibits significantly enhanced orientation ordering of both <i>a</i>- and <i>b</i>-axes compared with the PCL/PVC system. Grazing incidence reflection infrared spectroscopy analysis indicates that the PCL <i>c</i>-axis in the PCL/PVPh blend exhibits a higher degree of perpendicular orientation relative to the substrate surface compared with that in the PCL/PVC system. Fourier transform infrared spectroscopy reveals stronger intermolecular interactions between PCL and PVPh than those in PCL/PVC, which may account for the morphology and orientation difference of PCL crystallization in the two blends.

However, a quantitative understanding of the OFZ growth environment is generally lacking due to the difficulty of measuring the local sample temperatures during OFZ growth, as well as to the general lack of information about the temperature-dependent physical parameters needed to model heat transfer. To overcome these challenges, we apply a physics-based heat transfer model, parametrized by measurements from synchrotron experiments and a machine-learning (ML) algorithm, to simulate the temperature distributions of samples heated in an OFZ furnace in a vacuum environment. This model is used to quantitatively understand how the sample maximum temperature and temperature gradient (key parameters that influence the success of crystal growth) are affected by the rod size, rod shape, and heat-zone position on the rod.

Of particular interest is the ability to grow the metastable wurtzite crystal, which is commercially unavailable in semiconductors such as GaAs and SiGe. The successful growth of wurtzite GaAs nanowires has been demonstrated by precise control of the wetting contact angle of the catalyst particle. However, a recent discovery revealed an inherent limitation, known as the critical length, which restricts the maximum achievable aspect, length-to-diameter, ratio in wurtzite GaAs nanowire below 100. Here, we demonstrate the growth of wurtzite GaAs nanowire above the cirtical length with a stacking fault density of 10 SF/μm and precise crystal phase control down to the monolayer regime using Ga-pulses. The crystal phase control by Ga-pulsing is investigated as a function of pulse duration, frequency and position along the nanowire length. A pulse scheme is developed to stabilize the wurtzite crystal phase for aspect ratios up to nearly 200.
