Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

open access: yesAdvanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Physics of Solar Prominences

2005
We present the fundamental equations which govern the physics of quiescent solar prominences. The mechanical equilibrium of prominences is described by the equations of magneto-hydrostatics. The radiative properties of the structures have to be modelled by non-LTE equations.

Solar Physics: Overview

2020
Solar physics is one of the liveliest branches of astrophysics at the current time, with many major advances that have been stimulated by observations from a series of space satellites and ground-based telescopes as well as theoretical models and sophisticated computational experiments.

Solar–Terrestrial Physics

Physics Bulletin, 1973
S-I Akasofu and S Chapman London: Oxford University Press 1972 pp xxiii + 901 price £25 During the last few years of his life Sydney Chapman was, among many other activities, collaborating with S-I Akasofu in writing a book on solar–terrestrial physics. A first draft was sent to the Clarendon Press in April, 1970; the final version was not completed by
