dhkl is a function of the size and shape of the unit cell • dhkl is the vector drawn from the origin of the unit cell to intersect the crystallographic plane (hkl) at a 90° angle. – dhkl, the vector magnitude, is the distance between parallel planes of atoms in the family (hkl) – the diffraction peak position is a product

– These films tend to have less lattice strain and higher defect concentration, particularly mosaicity, because the relationship between the film and substrate is weaker. – Examples: GaN on Al 2 O 3, BiFeO 3 on LaAlO 3, Pb(Zr,Ti)O 3 on MgO – I have not yet found a good term to describe these types of films

Introduction to XRPD Data Analysis

• The diffraction data are reduced to a list of diffraction peaks • Peak search – Analysis of the second derivative of diffraction data is used to identify likely diffraction peaks – Peak information is extracted by fitting a parabola around a minimum in the second derivative – This method is fast but the peak information lacks precision

that the number of electrons recorded is proportional to the number of atoms in a given state. The basic tool for measuring the number of electrons recorded for an atomic state is the quantification region. Figure 2 illustrates a survey spectrum where the surface is characterised using a quantification table based upon values computed from regions.

Lecture 2 : Basics of Probability Theory

Lecture 2 : Basics of Probability Theory When an experiment is performed, the realization of the experiment is an outcome in the sample space. If the experiment is performed a number of times, different outcomes may occur each time or some outcomes may repeat. This “frequency of occurrence” of an outcome can be thought of as a probability.

SAR Imaging Basics 5 This is also a good time to point out that there are two different meanings for the term range in radar imaging.The first is the so -called slant range and refers to the range along the radar line-of-sight, as shown in Fig. 1-3. Slant ranges are measured along the line connecting the radar and the object being imaged, often
