如今，使用分形概念来理解各种生长现象，如分子束外延(MBE)或多孔介质中的流体流动，变得越来越重要。这本书介绍了基本的模型和概念，这些模型和概念是以教学的方式理解导致粗糙界面的各种成长过程所必需的。不熟悉该领域的读者可以阅读该文本。自然界提供了大量的粗糙表面和界面。同样，在各种技术上重要的生长技术中，如分子束外延，实验室中也会定期观察到粗糙表面。为了了解粗化现象的起源，最近发展了几种计算机模型和理论方法。这本书的主要目标是描述基本模型和理论，以及人们用来为特定增长过程建立模型的原则。此外，在描述了特定的生长模型后，作者展示了如何解决和回答诸如表面是否会粗糙、表面会有多粗糙以及如何表征这种粗糙度等问题。在介绍了研究生长模型所需的基本方法和工具后，作者详细讨论了两类现象：多孔介质中的流体流动和分子束外延。在这两种情况下，除了模型和分析方法外，作者还描述了相关的实验结果。这篇课文包含章节末尾的家庭作业问题，对于物理、材料科学、化学和工程方面的高级本科生、研究生和研究人员，特别是那些对凝聚态物理和表面生长感兴趣的人来说，将是无价的。
The use of fractal concepts in understanding various growth phenomena, such as molecular beam epitaxy (MBE) or fluid flow in porous media, is increasingly important these days. This book introduces the basic models and concepts that are necessary to understand in a pedagogical way the various growth processes leading to rough interfaces. The text will be accessible to readers not familiar with the field. Nature provides a large number of rough surfaces and interfaces. Similarly, rough surfaces are regularly observed in the laboratory during various technologically important growth technologies, such as MBE. In an attempt to understand the origin of the roughening phenomena, several computer models and theoretical approaches have recently been developed. The principal goal of this book is to describe the basic models and theories as well as the principles one uses to develop a model for a particular growth process. Furthermore, having described a particular growth model, the authors show how one can address and answer questions such as whether the surface will be rough, how rough it will be, and how to characterize this roughness. Having introduced the basic methods and tools needed to study a growth model, the authors discuss in detail two classes of phenomena: fluid flow in a porous medium and molecular beam epitaxy. In both cases, in addition to the models and analytical approaches, the authors describe the relevant experimental results as well. This text contains homework problems at the ends of chapters, and will be invaluable for advanced undergraduates, graduate students and researchers in physics, materials science, chemistry and engineering, and especially those interested in condensed matter physics and surface growth.
