TLDR
Detailed growth kinetics results are discussed, which illustrate that 'true' layer-by-layer (LBL) growth can only be approached, not fully met, even though many characterization techniques reveal interfaces with unexpected sharpness.Abstract:
Pulsed-laser deposition (PLD) is one of the most promising techniques for the formation of complex-oxide heterostructures, superlattices, and well controlled interfaces. The first part of this paper presents a review of several useful modifications of the process, including methods inspired by combinatorial approaches. We then discuss detailed growth kinetics results, which illustrate that 'true' layer-by-layer (LBL) growth can only be approached, not fully met, even though many characterization techniques reveal interfaces with unexpected sharpness. Time-resolved surface x-ray diffraction measurements show that crystallization and the majority of interlayer mass transport occur on timescales that are comparable to those of the plume/substrate interaction, providing direct experimental evidence that a growth regime exists in which non-thermal processes dominate PLD. This understanding shows how kinetic growth manipulation can bring PLD closer to ideal LBL than any other growth method available today.read more

Lithium/Sulfide All‐Solid‐State Batteries using Sulfide Electrolytes
TL;DR: The required properties of the sulfide electrolytes, such as the electrochemical stabilities of the electrolytes and the compatible electrode/electrolyte interfaces are highlighted, and the opportunities for sulfide-based ASSLBs are discussed.
Superlattices and microstructures
TL;DR: An abstract should be a single paragraph containing 100-150 words that briefly states the purpose of the research, the principal results and major conclusions and must be able to stand alone.

Growth and magnetoresistive properties of (LaMnO3)m(SrMnO3)n superlattices
TL;DR: In this paper, the superlattice properties of La 0.74Sr 0.26MnO3 were investigated using x-ray diffraction and electron microscopy, and it was shown that increasing Λ (to 21 ap) leads to a decrease in the Tc, the low-temperature magnetization, the magnetoresistance and the TMI.
