Pressure effects are studied on the fundamental indirect gap ( E g ), direct gap ( B 0 ), and next higher critical point ( B 0 ′ ) in InS single crystals by using a diamond‐anvil cell for the first time. A synchronized decrease of their energies is observed with pressure increasing up to 2 GPa. This unusual behavior is inferred partly due to a softening of InIn bond under pressure.
