This study examines current oscillations and resonances in nanocrystals of narrow-gap semiconductors, specifically lead sulfide (PbS) and indium antimonide (InSb). These phenomena were explored using scanning probe microscopy to analyze current-voltage characteristics (CVCs). Findings revealed quasi-periodic spikes and resonant peaks linked to the wave-like behavior of electrons (de Broglie process) and Bloch oscillations within the nanocrystals.
The results indicate that larger size quantization parameters correlate with more pronounced oscillation and resonance effects, showcasing a potential application in terahertz radiation generation modulated by ultra-short pulses. The study highlights the unique quantum behaviors within nanocrystals that contribute to advances in nanotechnology and semiconductor research. Such insights can lead to innovative developments in electronics, particularly in fields requiring precise electron transport and quantum-level control.
