Fieldselectronics

Fieldselectronics is a broad area of electronics that focuses on devices and systems whose operation is driven or controlled by physical fields such as electric, magnetic, or optical fields. The field emphasizes how field interactions enable sensing, actuation, modulation, and transduction, often linking materials science with device engineering. It encompasses both field-effect phenomena in traditional semiconductor devices and field-based approaches used in sensors, actuators, and communication components.

Key concepts in fieldselectronics include the use of electric fields to control charge carriers (as in field-effect transistors and capacitive sensors), magnetic fields to bias or read out magnetoresistive and Hall devices, and optical fields to modulate or detect light in photonic and optoelectronic components. Materials with strong field interactions—such as ferroelectrics, ferromagnets, piezoelectrics, and two-dimensional materials—are commonly explored to enhance performance.

Major device families associated with fieldselectronics include field-effect transistors (including MOSFETs and variants), Hall-effect and magnetoresistive sensors, capacitive and piezoelectric sensors, and optoelectronic modulators and detectors. MEMS and NEMS devices often rely on electrostatic, magnetic, or optical fields for actuation and sensing. In addition, field-selectable or field-tunable components enable reconfiguration of circuits without physical redesign, via gating, biasing, or optical control.

Applications span sensing and instrumentation, automotive and industrial electronics, communications, RF tunable components, and adaptive optics. Research challenges include materials integration with conventional CMOS, noise and drift of field-based devices, energy efficiency, thermal management, and scaling to smaller dimensions while preserving field control. Fieldselectronics aims to bridge fundamental field physics with practical, scalable electronic technologies.
