It presents a quasi systematic investigation of the influence of dimensionality changes from 1d to 3d via surfaces and 2d quantum wells on the physical properties of solids the aim of this book is to teach solid state physics through the use of problems and solutions giving orders of magnitude and answers to simple questions of this field. Do this for the lattice planes 3 2 1 and 1 2 3 solution the vector product of g h1 k1 l1 and g h2 k2 l2 defines a vector that is parallel to both planes h1 k1 l1 and h2 k2 l2 and is thus parallel to their intersection which is the lattice direction m n p. This english translation of understanding solid state physics originally written by the late author has been largely extended and updated based on the rapid development in materials science nanochemistry and solid state physicsa broad readership could benefit from this book including graduate students and scientists involved with solid state matter. Understanding solid state physics problems and solutions ist eine wunderbare und durchdachte sammlung von einfachen und fortgeschrittenen uebungsaufgaben die die studenten von einfachen konzepten in die tiefen der festkoeperphysik begleiten der leser erhaelt einen fundierten einblick durchgehend relevant fuer experimentalphysiker. Solids and their macroscopic electrical optical thermal properties understanding solid state physics problems and solutions the aim of this book is to teach solid state physics through the use of problems and solutions giving orders of magnitude and answers to simple questions of this field the numerous comments and problems in the
