As the condensed matter analog of Majorana fermion, Majorana zero-mode is well known as a building block of fault-tolerant topological quantum computing. In this review, we focus on the recent progress of Majorana experiments, especially experiments about semiconductor-superconductor hybrid devices. We first sketch Majorana zero-mode formation from a bottom-up view, which is more suitable for beginners and experimentalist. Then, we survey the status of zero-energy state signatures reported recently, from zero-energy conductance peaks, the oscillations, the quantization, and the interactions with extra-degrees of freedom. This paper also gives prospects on future experiments for advancing one-dimensional semiconductor nanowire-superconductor hybrid materials and devices.
