Single Crystal Investigations of Polymorphism and Disorder in CH3NH3PbI3
Photovoltaics are one of the most promising technologies for meeting future energy requirements. CH3NH3PbI3 was first used in a solar cell in 2009, which gave an efficiency of... -

Single-crystal analysis of disorder in deuterated and protonated mirabilite
Mirabilite (Na2SO4.10H2O) is relevant to many areas of geology, planetary science, and even the construction industry. It occurs naturally in evaporite deposits, and even as... -
Thermochromism in N-salicylideneanilines
N-salicylidineanilines are known to show thermochromic behaviour, which is currently postulated to arise from an intramolecular proton shift between the keto and enol form as... -
Atomic resolution holographic study of polycrystalline yttrium hydride
It is commonly accepted that the recording of holograms with atomic resolution requires singlecrystalline samples. Closer analysis, however, shows that the reduced information... -
Neutron Diffraction Studies on YbCu4Ga8
We discovered a new compound YbCu4Ga8 and the available laboratory single crystal data shows that it crystallizes in the tetragonal system. The asymmetric unit contains one Yb... -
High temperature superstructures in thermoelectric oxides
Sodium cobalate has emerged as one of the best thermoelectric materials. Our previous neutron Laue diffraction studies on SXD have found ordered arrays of multivacancy clusters,... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
Characterisation of diffuse scattering in β-Ti GUM metal
The goal of this proposal is to measure the diffuse scattering in Beta-Ti Gum Metal. We have measured the phonon dispersion curves and have found several soft-phonon anomalies... -
Structural Studies of 9-methyltriptycenes
We aim at obtaining reliable structural information for selected compounds from a series of four 9-methyltripticene derivatives. These compounds form in the solid state... -
H/D isotope effect on enamtiomers: the case of Alanine
In the current description of any molecular system based on the Schrodinger equation with a Hamiltonian accounting only for the electromagnetic forces, the structural properties... -
Understanding enhanced thermoelectric properties of sodium cobaltate doped by...
The thermoelectric power factor for (Na1-y¿My¿)0.8CoO2 is dramatically increased when M = Sr, but it is essentally unchanged from the pure compound when M = Ca. Our previous SXD... -
Martensite Variants and elastic Constants of Co-Ni-Ga Shape Memory Alloys
Pseudoelastic Co-Ni-Ga high-temperature shape memory alloys are characterized by a wide range of tunable transformation temperatures and lower processing costs compared to... -
Long-range cationic ordering in metal-organic perovskite solid solutions
The structure of the metal guanadinium formates is analogous to perovskite; the Cu compound is of particular interest as a potential multiferroic. We have recently demonstrated... -
Phonons from diffraction and normal mode analysis in HMT
With the overall aim of extending the information derivable in a neutron single crystal diffraction experiment beyond the static structure, we are proposing to perform a... -

Neutron diffuse scattering from multiferroic single crystal BiFeO3
BiFeO3 is a canonical multiferroic material. We know that local (nanoscale) order is crucial in explaining the behaviour of conventional ferroelectrics, and reciprocal space... -
Single Crystal Neutron Diffraction Study of a photo-active pyrene derivative
The compound proposed for this study is an interesting example of how strongly spectroscopic properties of pyrene derivatives in the solid state can depend on the crystal... -
Complexity in simplicity: disentangling Pb2+ disorder in PbS, PbSe and PbTe
We ask for 5 days on SXD to study the detailed crystal structures of PbS, PbSe and PbTe to resolve long-standing, topical controversies about the detailed behaviour of this...
