Case Presentation of Two Patients Compassionately Discharged, from Hospital to Home, Who Did Not Achieve Their Desired Home Death.

The objective of this case presentation is to identify factors that hinder home deaths after patients have been compassionately discharged from the hospital. It aims to shed light on modifiable factors that could facilitate a home death. Compassionate discharges differ from routine discharges as they are done to support the wishes of terminally ill patients to pass on at home.

Charge state-dependent symmetry breaking of atomic defects in transition metal dichalcogenides.

The functionality of atomic quantum emitters is intrinsically linked to their host lattice coordination. Structural distortions that spontaneously break the lattice symmetry strongly impact their optical emission properties and spin-photon interface. Here we report on the direct imaging of charge state-dependent symmetry breaking of two prototypical atomic quantum emitters in mono- and bilayer MoS by scanning tunneling microscopy (STM) and non-contact atomic force microscopy (nc-AFM).

Tailoring the Angular Mismatch in MoS Homobilayers through Deformation Fields.

Ultrathin MoS has shown remarkable characteristics at the atomic scale with an immutable disorder to weak external stimuli. Ion beam modification unlocks the potential to selectively tune the size, concentration, and morphology of defects produced at the site of impact in 2D materials. Combining experiments, first-principles calculations, atomistic simulations, and transfer learning, it is shown that irradiation-induced defects can induce a rotation-dependent moiré pattern in vertically stacked homobilayers of MoS by deforming the atomically thin material and exciting surface acoustic waves (SAWs).

Scalable Substitutional Re-Doping and its Impact on the Optical and Electronic Properties of Tungsten Diselenide.

Reliable, controlled doping of 2D transition metal dichalcogenides will enable the realization of next-generation electronic, logic-memory, and magnetic devices based on these materials. However, to date, accurate control over dopant concentration and scalability of the process remains a challenge. Here, a systematic study of scalable in situ doping of fully coalesced 2D WSe films with Re atoms via metal-organic chemical vapor deposition is reported.

Computation of the lattice Green function for a dislocation.

Modeling isolated dislocations is challenging due to their long-ranged strain fields. Flexible boundary condition methods capture the correct long-range strain field of a defect by coupling the defect core to an infinite harmonic bulk through the lattice Green function (LGF). To improve the accuracy and efficiency of flexible boundary condition methods, we develop a numerical method to compute the LGF specifically for a dislocation geometry; in contrast to previous methods, where the LGF was computed for the perfect bulk as an approximation for the dislocation.
