FIG. 1.

(a) Dependence of on pressure for two long, thick, high stress silicon nitride beams of similar vacuum frequency and (60 000), with different widths: and , (SEM shown in the inset). The vertical lines indicate the pressure range for which the Knudsen number is for the narrow (n) and wide (w) beam. (b) normalized by a fmf model, as a function of pressure for long, thick low stress silicon nitride beams, with widths of 86, 162, and . Deviations of 25% from the fmf model are marked at Kn numbers of 2.31, 1.95, and 0.81 , respectively.

(a) as a function of Kn for beams from Fig. 1, as well as a wide beam suspended over a smaller gap. Isobars for the devices from Fig. 1(b) are plotted, from top to bottom, at 860, 568, 329, and . (b) Dependence of on beam width for long, thick low stress silicon nitride beams with widths ranging from , and gap heights of 750, 660, 460, and .

dependence on air pressure for a long high stress beam, and its harmonics. (b) vs. frequency, at air pressures from for a long beam frequency-tuned using a chip-bending technique. Linear fits are shown. Inset: a compilation of vs at . for a mix of devices including fundamental modes of different length beams, stress-tuned beams, and harmonics covering a frequency range from , exhibiting from 17 to 600.
