A proposed mirrored shuffle layout pattern cancels systematic resistor gradient variations up to second order and allows monolithic integration of hundreds of matched resistors for precision analog circuits. A test circuit uses 15 000 subresistors an

We propose and demonstrate a resonant-tunneling diode (RTD) based memory cell in which N bits are stored in a series combination of N RTDs without internal node contacts. The slew rate of an applied voltage signal determines the circuit switching dyn

We develop a quantitative model for computation of the RHEED signal intensity during epitaxial growth. The growth surface is described in a way that naturally allows for tilted substrates. Oscillations in the computed RHEED signal during MBE growth e

We have fabricated arrays of resonant tunneling diodes based on InP substrates for exposure at room temperature with fluences of 3 MeV protons up to 7×1014 H+/cm2. Proton fluences below about 1×1013 cm−2 have little effect on the resonant tunneli
