  We performed systematic transport measurements on FeSe single crystals with
applying in-plane biaxial strain $\varepsilon$ ranging from -0.96% to 0.23%.
Biaxial strain was introduced by firmly gluing samples to various substrate
materials with different thermal expansion. With increasing $\varepsilon$,
structural and superconducting transition temperatures monotonically increased
and decreased, respectively. We analyzed magneto-transport results using a
compensated three-carrier model. The evaluated densities of hole and electron
carriers systematically changed with strain. This indicates that we succeeded
in controlling the band structure of single-crystalline FeSe.
