Description
Summary:We show how fabricated semiconductor heterostructures enable quantum particles to exhibit resilience to curved space, achieved through a suitable position-dependent mass distribution within the semiconductor. Following the proposed approach, we show that the first-order approximation of curved space requires a position-dependent mass distribution that is common for semiconductor heterostructures. For more complex structures of curved space, one has to consider a more exotic fabricated semiconductor. •Semiconductor heterostructure can resist space curvature for quantum particles.•Resisting curved space by heterostructures restores standard commutation relation.•Quantum potential quantifies heterostructure-curved space interplay.
