What is a superlattice and why is it important for nanoelectronics?




A superlattice is a man-made structure that consists of alternating layers of two different materials with nanometer thickness. By stacking these layers in a periodic pattern, one can create a new artificial material with novel electronic, optical, magnetic, or thermal properties that are different from those of the individual layers. For example, a superlattice can have a higher electron mobility, lower resistance, higher breakdown voltage, or enhanced photonic emission than its constituent materials.


Superlattices are important for nanoelectronics because they allow us to engineer new materials with desired characteristics that are not available in nature. Nanoelectronics is the branch of electronics that deals with devices and circuits that operate at the nanoscale level, where quantum effects become significant. Nanoelectronic devices can offer higher performance, lower power consumption, smaller size, and greater functionality than conventional electronic devices. Superlattices can enable nanoelectronic devices such as quantum well lasers, resonant tunneling diodes, quantum cascade lasers, quantum dot solar cells, spintronic devices, thermoelectric devices, and more.


The concept and history of superlattices




The concept of superlattices was first proposed by Leo Esaki and Raphael Tsu in 1970 . They suggested that by growing thin layers of two semiconductors with different band gaps on top of each other, one could create a new type of semiconductor with a periodic potential that forms mini-bands in the energy spectrum. These mini-bands could allow electrons to move faster and more coherently through the superlattice than through the individual layers, resulting in a negative differential conductance (NDC) phenomenon. NDC means that the current decreases as the voltage increases, which is useful for high-speed switching and amplification.


The first experimental demonstration of superlattices was achieved by Chang and Esaki in 1974 . They fabricated a superlattice of 10-nm-thick layers of GaAs and AlAs using molecular beam epitaxy (MBE), a technique that allows precise control of the layer thickness and composition. They observed NDC and oscillations in the current-voltage characteristics of the superlattice, confirming the theoretical predictions of Esaki and Tsu.


Since then, superlattices have been developed using various materials, such as metals, oxides, organic molecules, and carbon nanotubes. Superlattices have also been extended from one-dimensional structures to two-dimensional and three-dimensional structures, such as quantum wells, quantum wires, and quantum dots. Quantum wells are thin layers of a narrow band gap material sandwiched between two wider band gap materials, forming a potential well that confines electrons in one dimension. Quantum wires are narrow strips of a quantum well that confine electrons in two dimensions. Quantum dots are small islands of a quantum well that confine electrons in three dimensions.


The applications and advantages of superlattices in nanoelectronics




Superlattices have many applications and advantages in nanoelectronics, such as:


  • Quantum well lasers: These are lasers that use quantum wells as the active medium, where electrons and holes recombine and emit photons. Quantum well lasers have lower threshold currents, higher efficiency, longer lifetimes, and narrower emission spectra than conventional lasers.



  • Resonant tunneling diodes: These are diodes that use quantum wells or quantum dots as the tunneling barriers, where electrons can tunnel through the barriers only when their energy matches the discrete energy levels of the quantum wells or dots. Resonant tunneling diodes have very high peak-to-valley current ratios, which make them suitable for logic circuits, memory devices, oscillators, and sensors.



  • Quantum cascade lasers: These are lasers that use a series of quantum wells as the active medium, where electrons cascade down from one quantum well to another and emit photons at each transition. Quantum cascade lasers can operate at different wavelengths in the infrared and terahertz regions, which are useful for spectroscopy, imaging, communication, and security applications.



  • Quantum dot solar cells: These are solar cells that use quantum dots as the light-absorbing material, where electrons can be excited to higher energy levels by absorbing photons with different wavelengths. Quantum dot solar cells have higher efficiency, lower cost, and tunable band gaps than conventional solar cells.



  • Spintronic devices: These are devices that use the spin of electrons as well as their charge to store and manipulate information. Spintronic devices can offer higher speed, lower power consumption, and higher density than conventional electronic devices. Superlattices can be used to create spin-polarized currents, spin filters, spin valves, spin transistors, and spin qubits.



  • Thermoelectric devices: These are devices that convert heat into electricity or vice versa by exploiting the Seebeck effect or the Peltier effect. Thermoelectric devices can be used for waste heat recovery, cooling, heating, and power generation. Superlattices can enhance the thermoelectric performance by reducing the thermal conductivity and increasing the electrical conductivity and the Seebeck coefficient.
