Characterization of oxide trap and interface trap creation duringhot-carrier stressing of n-MOS transistors using the floating-gatetechnique

A technique has been developed to differentiate between interface states and oxide trapped charges in conventional n-channel MOS transistors. The gate current is measured before and after stress damage using the floating-gate technique. It is shown that the change in the I_g-V_g characteristics following the creation and filling of oxide traps by low gate voltage stress shows distinct differences when compared to that which occurs for interface trap creation at mid gate voltage stress conditions, permitting the identification of hot-carrier damage through the I_g- V_g characteristics. The difference is explained in terms of the changes in occupancy of the created interface traps as a function of gate voltage during the I_g-V _g measurements     

Electro-optical trap for dipolar excitons

An electro-optical trap for spatially indirect dipolar excitons is implemented in a GaAs/AlAs Schottky diode with a 400-?-wide GaAs single quantum well. In the presence of bias voltage applied to the gate, the trap for excitons appears upon annular illumination of the structure by a continuous-wave or pulsed laser generating hot electron-hole pairs in the quantum well. A barrier for excitons collected inside the illuminated ring appears due to screening of the applied electric field by nonequilibrium charge carriers within the excitation region. Excitons are collected inside the ring due to the ambipolar drift of carriers and the dipole-dipole repulsion of excitons in the optically pumped region. For dipolar excitons thus accumulated in the middle of the ring-shaped electro-optical trap, significant narrowing of the luminescence line is observed with increasing excitation density, which indicates the collective behavior of the excitons.

Kinetics of trapping,detrapping, and trap generation

The trapping and detrapping of charge in the oxides have been studied for two decades. While there has been a lot of progress in understanding the mechanisms responsible for charge trapping and detrapping in these oxides, it is still not fully understood. For example, even under low field injection conditions first order trapping kinetics do not accurately model the observed data. Under high field injection the situation is exacerbated by the generation of additional trapping sites during the injection process, which is also not completely understood. The paper presents a review of the kinetics of trapping and detrapping and describes various models that have been proposed to explain experimentally observed trapping-detrapping behavior.     

Avalanche breakdown and surface deep-level trap effects in GaAsMESFET's

Time-dependent numerical simulations have been performed to investigate avalanche breakdown and surface deep-level trapping effects in GaAs MESFETs. The model is based on a combination of bipolar drift-diffusion transport, impact ionization, and a dynamic surface charging mechanism. A realistic trapping process is introduced into the surface trap model from which the spatial distribution of surface charge density is determined. The basic breakdown mechanisms, gate-bias-dependent breakdown voltages, and effects of surface charges are demonstrated. It is shown that the surface deep-level traps have a pronounced effect on the breakdown phenomenon

Fabrication of a pneumatically driven single-cell trap

This paper describes the creation of a pneumatically driven single-cell trap and its ability to trap a live single cell. The cell-trap device consists of a pneumatic vibrator array and a trap chamber used to trap single cells. The entire structure was manufactured with polydimethylsiloxane (PDMS). External compressed air was used to actuate the pneumatic vibrators. The magnitude and frequency of the pneumatic force were controlled by programmable electromagnetic valves. The live cell in the trap chamber was manipulated using the velocity field of the cell media induced by deformation of the vibrator diaphragm. The cell was successfully trapped in the central equilibrium region of the device, at which point the axial velocity fields generated by the vibrators were minimized. The intracellular calcium response of a single cell induced by mechanical stimuli during cell trapping was measured to verify the effectiveness of the pneumatic cell trap as a stress-free trapping method. The results showed that the internal signaling in the cell was sensitive to the extracellular physical environment. Since the measured intensity of the intracellular calcium of the single cell was very minor, the pneumatic cell trap described in this paper was categorized as a harmless trapping method.
