Band‐to‐band tunneling (BTBT) devices with superior subthreshold swing directly related to on/off switching speed and power consumption efficiency have emerged as a breakthrough of the limitation in conventional metal‐oxide‐semiconductor field‐effect transistors (MOSFETs). However, it is difficult to reach a higher level of electrical characteristics with only a combination of materials based on their intrinsic characteristics. External forces, such as electric fields, light, and temperature, can modulate the electron and hole concentration and control the tunneling probability and the electrical characteristics of heterostructure electronics. Recent articles employing external forces to improve the BTBT performance and demonstrate the mechanism of BTBT devices are summarized with five representative external forces. Moreover, the utility of the external force‐induced performance improvement of the BTBT device is also discussed by providing various applications.

“…In recent years, using stainless steel (SS) as a conductive and exible substrate has attracted some research. [18][19][20][21] It has advantages of easy availability at low cost and high melting point (∼1300 °C), which enables the synthesis of CNTs at a wide temperature range. Furthermore, SS contains catalytic elements (e.g., Fe), making it possible to achieve direct CNT growth without additional buffer layers or catalysts.…”

Vertically aligned carbon nanotubes arrays were synthesized via catalytic chemical vapor deposition technique. An opportunity to decreasing of acetylene as a carbon precursor contain down to 0.2% was demonstrated. An iron acetate as an alternative catalyst was proposed. Diameters of carbon nanotubes were estimated by them Raman spectra. Considering resonant behavior of radial breathing modes and them significant environment influencing, an approach based on а profile analyzing of G-band was offered to revel of nanotubes diameter distribution features.
