About the Edition

The double barrier resonant tunneling diode (DBRTD) is one of several devices currently being considered by the semiconductor industry as a replacement for conventional very large scale integrated (VLSI) circuit technology when the latter reaches its currently perceived scaling limits. The DBRTD was one of the first and remains one of the most promising devices to exhibit a room temperature negative differential resistance (NDR); this non-linear device characteristic has innovative circuit applications that will enable further downsizing. Due to the expense of fabricating such devices, however, it is necessary to extensively model them prior to fabrication and testing. Two techniques for modeling these devices are discussed, the Thomas-Fermi and Poisson-Schroedinger theories. The two techniques are then compared using a model currently under development by Texas Instruments, Incorporated.

Further, there had been some work on observing the resonant tunnelling into quantum wells in a multiple quantum well laser but without the explicit addition of a double barrier RTD. Tunnelling has been used to achieve large modulation bandwidths, 98 . Nobuya Mori. Professor, Graduate School of Engineering, Osaka University K. Taniguchi, and C.

Double barrier devices We now consider a resonant device obstructed using two barriers with a well in between. The barriers have a thickness of 50A, and the well has a width of A. Comparing Figure 28 with the experimental data in the right panel of Figure 4, we see that our calculated currents are somewhat greater than the experimental.

A resonant-tunneling diode (RTD) is a diode with a resonant-tunneling structure in which electrons can tunnel through some resonant states at certain energy levels.

The current–voltage characteristic often exhibits negative differential resistance regions. All types of tunneling diodes make use of quantum mechanical teristic to the current–voltage relationship. In this research article, analytic model of resonant tunnelling diode (RTD) is simulated for two different structures, i.e.

single barrier (1B) RTD and double barrier (2B) RTD. A graded emitter and thin barriers were introduced in GaInAs/AlAs double-barrier resonant tunneling diodes for reductions of the transit time in the collector depletion region and the. This book gives a comprehensive description of the physics and applications of resonant tunnelling diodes.

The opening chapters of the book set out the basic principles of coherent tunnelling theory. The effects of impurity scattering, femtosecond dynamics, non-equilibrium distribution and intrinsic bistabilities are then described in detail.

Diodes [2] In simple terms, a diode is a device that restricts the direction of flow of charge carriers (electrons in this class) [1]. Essentially, it allows an electric current to flow in one tunneling, thus allowing amplification of signals and very simple bistable circuits.

Therefore, these types of RTDs enable resonant sharpness to be narrower compared with double-barrier RTDs (Nakagawa et al, ). As a result, large negative differential conductance is expected against small peak current density.

The triple-barrier RTD is designed to get negative differential conductance similar to double-barrier : T. Ouchi. On the way to develop a complete full-band quantum transport simulation using the Pauli Master Equation, we show our present results on ID n-i-n resistors, ID double barrier resonant tunneling diodes (DBRTD), and 2D double-gate field effect transistors (DGFETs) using a simplified parabolic, spherical effective-mass band-structure model accounting for nonpolar scattering.
