Molecular (nano) electronics focuses on fundamental, applied, and experimental research and technology developments in devising and implementing novel high-performance enhanced-functionality atomic or molecular devices, modules and platforms (systems), and high-yield bottom-up fabrication.

Molecular electronics centers on the following:
  1. Invention of novel devices based on a new device physics
  2. Utilization of the exhibited unique phenomena, effects, and capabilities
  3. Devising of enabling topologies, organizations, and architectures
  4. Bottom-up high-yield fabrication
At the device level, the key differences between molecular and microelectronic devices are the following:
  1. Device physics and phenomena exhibited
  2. Effects, capabilities, and functionality utilized
  3. Topologies and organizations attained
  4. Fabrication processes and technologies used
Microelectronic vs Molecular Electronic Devices
In microelectronic devices, individual molecules and atoms do not depict the overall device physics and do not define the device performance, functionality, and capabilities. In contrast, in molecular devices, individual molecules and atoms define the overall device physics and depict the device performance, functionality, capabilities, and topologies.

There are fundamental differences at the system level. In particular, molecular electronics leads to novel organizations, advanced architectures, High-yield affordable nanoelectronics technologies are expected to emerge and mature ensuring superior performance. Existing superb bimolecular processing/memory platforms and progress in molecular electronics are assured evidence of the fundamental soundness and technological feasibility of MICs and MPPs. Some data and expected developments, reported in Figure 1.5, are subject to adjustments because it is difficult to accurately foresee the fundamental developments and maturity of prospective technologies because of the impact of many factors.

However, the overall trends are obvious and likely cannot be rejected. Having emphasized the emerging molecular (nano) electronics, it is obvious that solid-state microelectronics is a core twenty-first century technology. CMOS technology will remain a viable technology for many decades even as the limits will be reached and envisioned nanoelectronics will mature. It may be expected that by 2025–2030 the core modules of super-high-performance processing (computing) platforms may be implemented using MICs. However, microelectronics and molecular electronics will be complimentary paradigms, and MICs will not diminish the use of ICs. Molecular electronics and MPPs are impetuous, revolutionary (not evolutionary) changes at the device,
system, and technological levels.

The foreseen revolutionary changes towards Mdevices are analogous to the abrupt change from the vacuum tube to the solid-state transistor
