Abstract

This paper reports the preliminary feasibility study of room temperature vulcanization (RTV) 566 for its application as a ldquospringrdquo for in situ height adjustment in our proposed design for an array of Schottky emitters. The reliability of the RTV 566 is tested in terms of its viscoelastic properties for thicknesses of 95, 142, and 195 mum. The shear modulus varied a little with the thickness. Although the RTV 566 shows a very little hysteresis, it shows a clear sign of viscoelastic behavior, rendering it unsuitable for the application. The viscoelastic behavior of the RTV 566 is modeled with the Findley model.
