WebNov 14, 2024 · Typical RBS/C spectra for the a-plane GaN sample implanted using different Ar-fluences are shown in Figure 2a. The backscattering yield of the as-grown sample is very low. Minimum yields well below 2% were measured close to the surface for all three sample materials, evidencing excellent crystalline quality along the growth direction.
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions … See more Rutherford backscattering spectrometry is named after Lord Rutherford, a physicist sometimes referred to as the father of nuclear physics. Rutherford supervised a series of experiments carried out by Hans Geiger See more We describe Rutherford backscattering as an elastic, hard-sphere collision between a high kinetic energy particle from the incident beam (the projectile) and a stationary particle located in the sample (the target). Elastic in this context means that no energy is … See more The energy loss of a backscattered ion is dependent on two processes: the energy lost in scattering events with sample nuclei, and the … See more While RBS is generally used to measure the bulk composition and structure of a sample, it is possible to obtain some information about the structure and composition of the sample surface. When the signal is channeled to remove the bulk signal, careful … See more An RBS instrument generally includes three essential components: • An ion source, usually alpha particles (He ions) or, less commonly, protons. • A linear particle accelerator capable of accelerating incident ions to high energies, usually in the range 1-3 MeV.
