“…As was shown in works [17][18][19], the inverse lifetime of donor electrons at shallow donors in GaAs can be of the order of 10 7 s −1 . For V 0 ≈ 0.94 and Ω 0 ≈ 0.58, we obtain Λ Ω0 R ′′ x ω pl ≈ 5.28 × 10 9 s −1 .…”

“…This instability has been studied experimentally [7][8][9]. Another class of objects, which are active in the THz spectral range, includes quantum dots [10][11][12][13], molecules and some molecular compounds [14][15][16], shallow impurity centers [17][18][19], and so forth. For brevity, let us call such "zero-dimensional" objects as nanoparticles (NPs).…”

“…Iншим класом об'єктiв, що є активними в THz областi спектра, є квантовi точки [10][11][12][13], молекули та деякi молекулярнi сполуки [14][15][16], мiлкi домiшковi центри [17][18][19] тощо. Для стислостi, такi "нульвимiрнi" об'єкти далi будемо називати наночастинками (NP).…”

“…У роботах [17][18][19] показано, що донорнi електрони на мiлких донорах в GaAs можуть мати обернений час життя близько 10 7 c −1 . У випадку коли V 0 ≈ 0, 94 та Ω 0 ≈ 0, 58 ми отримуємо Λ Ω0 R x ω pl ≈ 5, 28 • 10 9 с −1 .…”

“…These are well below the LO phonon energy ͑36 meV, 8.7 THz͒, and have long lifetimes ͑T 1 = 350 ns͒. 7,8 Cole et al demonstrated Rabi oscillations in ensembles of shallow donors in GaAs, using photoconductivity as the measure of the excited state population. 6 In their measurements, coherent transfer of the electron population to the excited state was accomplished on the scale of tens of ps.…”
