Molecular and framework dynamics in CH3NH3PbBr3 - Raman and neutron scattering
Organic-inorganic perovskites have recently been shown to be potentially efficient and inexpensive photovoltaics. These materials undergo a series of structural transitions and... -
Structural phase transition in SnSe with ultra low thermal conductivity
SnSe has recently been reported to have very good thermoelectric performance. This is linked to an ultralow thermal conductivity and occurs in the B-phase (ZT > 2 above 800... -
Phase transitions in RbBi2Ti2NbO10
Ferroelectric materials, in which the polarization may be switched, are an important class of compounds due to their academic and technological relevance. The mechanisms that... -
Microstructural orientation mapping with a neutron beam
We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have... -
