Measurement of the effective temperature of majority carriers under injection of hot minority carriers in heterostructures
نویسنده
چکیده
We propose and demonstrate a purely electrical method for measuring the effective temperature T, of majority carriers under the injection of hot minority carriers. The T, of holes in a thin p-type InGaAs layer, heated by electron injection from an InAlAs layer in a three-terminal lattice-matched heterostructure, was determined by measuring the thermionic emission current of holes over another specially designed InGaAs/InAlAs barrier. At T=77 K, we observed an overheating T, T of over 50 K, even at moderate injection power levels.

We study picosecond carrier transport dynamics induced by 200 fs 1.55 mm optical pulses in charge injection transistor structures. We propose and demonstrate a new optoelectronic method for exploring the interactions of hot majority carriers and cold minority carriers, as well as the optical control of real space transfer in these devices. The minority holes photogenerated in the channel produc...

Human T lymphotropic virus type I (HTLV-I) is a retrovirus which is associated with adult T cells leukaemia (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in a minority of HTLV-I-infected individuals. It is not clear why a minority of HTLV-I-infected individuals develop HAM/TSP and majority remains lifelong carriers. It seems that the interaction between the v...
متن کاملHigh-temperature thermoelectric transport at small scales: Thermal generation, transport and recombination of minority carriers
Thermoelectric transport in semiconductors is usually considered under small thermal gradients and when it is dominated by the role of the majority carriers. Not much is known about effects that arise under the large thermal gradients that can be established in high-temperature, small-scale electronic devices. Here, we report a surprisingly large asymmetry in self-heating of symmetric highly do...

Todaychr('39')s human life is undeniably dependent on satellites that have being sent to Earthchr('39')s orbit by space carriers. Delivery of any kind of cargo to space must be carried out by carriers, which are designed and optimized for the best energy consumption mood. One of the optimization steps in space carriers engine is to use porous materials in the engine injector plate. In this pap...
