A transition from an и-type to a /?-type conductivity due to a uniaxial strain has been detected in a gapless semiconductor. Formed due to a uniaxial strain, the lateral extrema of the valence band trap the holes with small effective masses, causing the hole mobility to be comparable to the electron mobility.
