The measured linewidths are consistent with those predicted by the two beam theory of ECP intensity when the affects of the incident beam divergence, , are accounted for. The appearance of ECP lines from very high order reflections is an indication that the limit of the reciprocal lattice ...
The L3-32 line, on one hand, has a high intensity, but its natural linewidth is not precisely known85. The N2,3-32 lines, on the other hand, have a low intensity, but their natural linewidth is negligible compared with spectral broadening caused by variations in the electric potential. ...
Full size image One of the outstanding phonon characteristics of halide perovskites is their low optical phonon frequencies, attributable to the heavy lead ions. Furthermore, the linewidth of the phonon absorption is very broad at room temperature, indicating that the optical phonons are overdamped40,...
For adenine, the properties of theπ-cation in the glass and ice systems parallel those for the guanine cation. In the glass, the ESR singlet linewidth from adenine is ∼0.2 mT smaller than that from guanine (Sevilla and Mohan, 1974), so the unpaired-electron density must reside mainly ...
We present an study of the electron–phonon (e–ph) coupling and its contribution to the phonon linewidths and to the lifetime broadening of excited electron and hole states in bulk Pd. The calculations, based on density-functional theory, were carried out using a linear-response approach in...
An analysis is made of fundamental laser line broadening due to random spontaneous emission of radiation and amplification of thermal radiation noise in terms of a classical fluctuating field phasor model; a general expression for the intrinsic linewidth is derived in terms of radiation noise source ...
These linewidths are only several times larger than the radiative relaxation rate of the D0X complex (Finkman et al., 1986). D0 Zeeman pairs A, A* and B, B* can be first identified in the PLE spectra using the known g-factor of the electron spin. To ensure that these are in fact...
Linewidth evolution with base dose for 40 nm wide grid lines corresponding to processing conditions (130 °C/0.2n), (150 °C/0.2n), (170 °C/0.26n). Inset shows actual patterns (top image corresponds to condition with highest PEB, and bottom image with lowest). b. Average lateral gain...
We derive a general expression for the intrinsic linewidth, given in terms of the spectral power of the radiation noise source, which can be classical or quantum mechanical in nature. In the case of a two-level atomic laser, we recover by the use of Einstein relations, the traditional ...
