Stacking-dependent energetics and electronic structure of ultrathin polymorphic V2VI3 topological insulator nanofilms
Topological insulators represent a paradigm shift in surface physics. The most extensively studied Bi2Se3-type topological insulators exhibit layered structures, wherein neighboring layers are weakly bonded by van der Waals...

Lattice-mismatched heteroepitaxy of IV-VI thin films on PbTe(001)
The chalcogenides of tin and lead (SnS, SnSe, SnTe, PbS, PbSe, and PbTe) have applications ranging from solar cells to thermoelectrics. Taking rocksalt structured PbTe(001) as the substrate, we explore the coherent...

Anharmonicity in the High-Temperature Cmcm Phase of SnSe
The layered semiconductor SnSe is one of the highest-performing thermoelectric materials known. We demonstrate, through a first-principles lattice-dynamics study, that the high-temperature Cmcm phase is a dynamic average over...

Levetiracetam-induced eosinophilic pneumonia.
Levetiracetam is widely regarded as a benign antiepileptic drug, compared to older antiepileptic medication. We report a case of eosinophilic pneumonia due to levetiracetam use in a non-smoking woman aged 59 years with no...

Identification of critical stacking faults in thin-film CdTe solar cells

Cadmium telluride (CdTe) is a p-type semiconductor used in thin-film solar cells. To achieve high light-to-electricity conversion, annealing in the presence of CdCl2 is essential, but the underlying mechanism is...

Elucidating the Mechanism of Fatigue Crack Acceleration Following the Occurrence of an Underload

Fatigue Crack Growth Rate (FCGR) is altered by a single anomalous load exceeding cyclic maximum (Overload) or compressive load below cyclic minimum (Underload). The authors study fatigue crack acceleration due to a single...
