The application of modern materials to electronic components
J. M. Herbert, R.G. Martin · Journal of the British Institution of Radio Engineers · 1961
New developments in component materials and techniques are discussed under the following headings: capacitors (ceramic disc, barrier layer and tantalum electrolytic); piezoelectric devices (filters); inductive devices (core, parametric and transformer techniques); semi-conductors (tunnel diode, variable capacitance diode, silicon controlled rectifier, thermo-electric components, solar cell, Hall effect); information storage systems (square loop ferrites); microminiature devices (component substrate, vacuum deposition, solid circuits). Transistors and thermionic tubes are not considered.
