Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Three-dimensional theory of stimulated Raman scattering

open access: yes, 2009
We present a three-dimensional theory of stimulated Raman scattering (SRS) or superradiance. In particular we address how the spatial and temporal properties of the generated SRS beam, or Stokes beam, of radiation depends on the spatial properties of ...

Giant Intrinsic Chirality Amplification of Aqueous Lead Halide Perovskite Nanocrystals via H‐Bond Driven Self‐Assembly Superstructures

open access: yesAdvanced Functional Materials, EarlyView.
Water‐assisted monoclinic CsPbBr3 transformation strategy is applied for synthesizing aqueous CsPbBr3/CsPb2Br5 nanocrystals with superior water‐repellent and excellent optical property. Low temperature enhanced hydrogen bonding network self‐assembled CsPbBr3/CsPb2Br5 nanocrystals into asymmetric superstructures, which exhibit notable circularly ...

Evanescent stimulated Raman scattering in benzene-immersed fluorophosphate optical nanofibers [PDF]

open access: yesEPJ Web of Conferences
Optical nanofibers (ONFs) made from fluorophosphate glass (OHARA - FPM) enable strong confinement, low losses, and enhanced evanescent fields for nonlinear optics. We show that the HE₁₁ mode achieves high Raman gain (11.62 m−1·W−1) in a compact 10 cm ONF

Spontaneous and Stimulated Raman Scattering near Metal Nanostructures in the Ultrafast, High-Intensity regime

open access: yes, 2013
The inclusion of atomic inversion in Raman scattering can significantly alter field dynamics in plasmonic settings. Our calculations show that large local fields and femtosecond pulses combine to yield: (i) population inversion within hot spots; (ii ...

Generation of spin currents via Raman scattering [PDF]

open access: yes, 2005
We show theoretically that stimulated spin flip Raman scattering can be used to inject spin currents in doped semiconductors with spin split bands. A pure spin current, where oppositely oriented spins move in opposite directions, can be injected in ...

Stimulated Raman Scattering

open access: yes, 1975
Stimulated Raman scattering was accidentally discovered by Woodbury and Ng in 1962 [7.1]. In studying Q-switching of a ruby laser by a nitrobenzene Kerr cell, they detected intense infrared radiation emitted from the Kerr cell, whose origin was not immediately identified.

Observation of Two‐Photon Resonant Raman Scattering via the Biexciton Level in Two‐Dimensional Halide Perovskite (C6H5C2H4NH3)2PbI4

open access: yesAdvanced Functional Materials, EarlyView.
Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

Inducing an optical Feshbach resonance via stimulated Raman coupling

open access: yes, 2004
We demonstrate a novel method of inducing an optical Feshbach resonance based on a coherent free-bound stimulated Raman transition. In our experiment atoms in a Rb87 Bose-Einstein condensate are exposed to two phase-locked Raman laser beams which couple ...
