Each of these signals has its own detector in the SEM, Scanning electron microscopy and spatially resolved cathodoluminescence were used to study porous silicon prepared by electrochemical degradation in aqueous HF of epitaxial p-type silicon grown on {100} silicon substrates. Scanning electron microscopy revealed the porous silicon to be non-uniform. 2016-02-01 Surface Spectroscopic Techniques 1. Surface is usually more than _____ atomic layer deep and is a region of ________ atomic potentials. a) One, uniform b) One, non-uniform b) Two, uniform d) Two, non-uniform Answer: b Explanation: Surface is more than one atomic layer deep and is a region of non-uniform 2020-12-02 Explanation: In scanning electron microscope (SEM), the surface of the specimen is irradiated with a very narrow beam of electrons. Such irradiations causes low energy (secondary) electrons to be ejected from the specimen which can then be collected on a positively-charged plate or anode thereby generating an electric signal.
