Effect of phonon-phonon interactions on localization.
We study the heat current J in a classical one-dimensional disordered chain with on-site pinning and with ends connected to stochastic thermal reservoirs at different temperatures. In the absence of anharmonicity all modes are localized and there is a gap in the spectrum. Consequently J decays exponentially with system size N. Using simulations we find that even a small amount of anharmonicity ...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولPhonon Bottleneck Identification in Disordered Nanoporous Materials
Nanostructured materials are promising as thermoelectrics since thermal transport can be suppressed with little degradation in electrical properties, a crucial requirement for high-efficiency thermal energy conversion. Porous materials offer a flexible platform thanks to their extensive range of possible configurations and robust nature compared to other nanostructures. Although there has been ...
متن کاملPhonon anomalies in some iron telluride materials
The detailed temperature dependence of the infrared-active mode in Fe1.03Te (TN 68 K) and Fe1.13Te (TN 56 K) has been examined, and the position, width, strength, and asymmetry parameter have been determined using an asymmetric Fano profile superimposed on an electronic background. In both materials the frequency of the mode increases as the temperature is reduced; however, there is also a slig...
