Tensometric Characteristics of GaSb Strain Gauges

in this paper presents the results of studies n-and p-type conductivity GaSb whiskers with orientation [111]. It was shown that, $\mathbf{n}$ - and p-types conductivity GaSb whiskers have high strain sensitivity and efficiency in a wide temperature interface $(-160 \div+100)^{\circ} \text{C}$. Tensometric characteristics are investigated for n-type GaSb whiskers with resistivity $0.002 \div 0.048$ Ohm $\times$ cm and p-type conductivity with resistivity $0.007 \div 0.15 \text{Ohm} \times \text{cm}$ in a wide range of range deformations ($\varepsilon=\pm 1.2 \times 10^{-3}$ rel. units) and temperature $-100 \div+100^{\circ} \text{C}$. GaSb whiskers is tested in a dynamic mode with a frequency of 50 to 100Hz at deformations $\varepsilon=5 \times 10^{-4}$ rel. units showed that they support at least 10
