Field Stability in Direct Modulation of Semiconductor Laser
Hoang Nam Nhat
We studied the rate equations of direct modulation laser and showed that it may be reduced to the special case when spontaneous carrier decay rate is equal to the photon decay rate…
Solving the De Prony's Problem of Separation of the Overlapping Exponents in DLTS
Hoang Nam Nhat
This paper presents the solution to the De Prony's problem of separation of the overlapping exponents using the binomial coefficient as the weighting factors. The algebraic structu…
Reference levels, signal forms and determination of emission factor in DLTS
Hoang Nam Nhat
The existence of reference levels of signals which determine directly the temperature dependence of emission factor in deep level transient phenomena is discussed. The basic algebr…

This paper presents the bond valence calculation for several perovskite systems and describes the evidences for a valence charge transfer process in these compounds. The reviewing…
On several correlation integrals of the deep level transients
Pham Quoc Trieu, Hoang Nam Nhat
This works presents the theoretical study on several correlation integrals of the capacitance transients of the deep levels. The deconvolution of the transient signals was the majo…
