Low thermal conductance platforms for mK tunnelling coolers [PDF]
The impact of the O2 content in SF6-O2 gas mixtures on the etch rate and sidewall profile of Silicon (Si), Germanium (Ge) and phosphorous doped Germanium (Ge:P) in reactive ion etching has been studied.

Advanced Materials, EarlyView.Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators
Advanced Materials, EarlyView.A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.

Electron–phonon processes of the silicon-vacancy centre in diamond
New Journal of Physics, 2015 We investigate phonon induced electronic dynamics in the ground and excited states of the negatively charged silicon-vacancy ( ${\rm Si}{{{\rm V}}^{-}}$ ) centre in diamond.

The influence of NH4 doping on the elastic properties of RbH2AsO4 crystals
Scientific ReportsWe report a systematic study of the elastic and dynamic properties of mixed Rb1-x(NH4)xH2AsO4 (RADA) crystals using high-resolution Brillouin light scattering over a broad temperature range (40–300 K). By varying the ammonium concentration, we reveal how

Examining Electron-Boson Coupling Using Time-Resolved Spectroscopy
Physical Review X, 2013 Nonequilibrium pump-probe time-domain spectroscopies can become an important tool to disentangle degrees of freedom whose coupling leads to broad structures in the frequency domain.

Controlled Growth of Boron Nitride in Various Phases
Advanced Materials Interfaces, EarlyView.Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...

Recombination of localized quasiparticles in disordered superconductors
Nature CommunicationsDisordered superconductors offer new impedance regimes for quantum circuits, enable a pathway to protected qubits, and can improve superconducting detectors due to their high kinetic inductance and sheet resistance.

Paramagnetic relaxation: Direct and Raman relaxation of spin S=12
Journal of Magnetic Resonance OpenParamagnetic relaxation in solids is a vast subject, about as vast as the range of manifestations of electron spin in matter. It is a complex subject as well: it is the interface between paramagnetic centres – be it transition metal ions, radicals or ...
