• Abstract: The continuous miniaturisation of metal-oxide-semiconductor field-effect transistors (MOSFETs) from long- to short-channel architectures has advanced beyond the predictions of Moore's Law. Continued advances in semiconductor electronics, even near current scaling and performance boundaries under cryogenic conditions, are driving the development of innovative device paradigms that enable ultra-low-power and high-speed functionality. Among emerging candidates, the Josephson Junction Field-Effect Transistor (JJFET or JoFET) provides an alternative by integrating superconducting source and drain electrodes for efficient, phase-coherent operation at ultra-low temperatures. These hybrid devices have the potential to bridge conventional semiconductor electronics with cryogenic logic and quantum circuits, enabling energy-efficient and high-coherence signal processing across temperature domains. This review traces the evolution from Josephson junctions to field-effect transistors, emphasising the structural and functional innovations that underpin modern device scalability. The performance and material compatibility of JJFETs fabricated on Si, GaAs, and InGaAs substrates are analysed, alongside an assessment of their switching dynamics and material compatibility. Particular attention is given to superconductor-silicon-superconductor Josephson junctions as the active core of JJFET architectures. By unfolding more than four decades of experimental progress, this work highlights the promise of JJFETs as foundational building blocks for next-generation cryogenic logic and quantum electronic systems.

  We propose a one-dimensional electronic nanodevice inspired in recently fabricated semiconductor-superconductor-ferromagnetic insulator hybrids. We show that the device can be tuned across spin- and fermion parity-changing QPTs by adjusting the FMI layer length orange and/or by applying a global backgate voltage. Our findings suggest that these effects are experimentally accessible and offer a robust platform for studying quantum phase transitions in hybrid nanowires.

  Electromagnetically induced transparency (EIT) is a phenomenon that can provide strong and robust interfacing between optical signals and quantum coherence of electronic spins. We show that EIT can be established with high visibility also in this material platform upon careful design of the measurement geometry. Our work provides an understanding of EIT in multi-level systems with significant inhomogeneities, and our considerations are valid for a wide array of defects in semiconductors.
