- description:
- Analyze recombination mechanisms at deep centers using configuration coordinate diagrams. Use when determining whether recombination is radiative or nonradiative, calculating temperature-dependent capture cross sections, or evaluating electron-lattice coupling strength.
Deep Center Recombination Analysis
When to Use
- Determining recombination mechanism (radiative vs nonradiative) at deep centers
- Calculating temperature-dependent capture cross sections for deep traps
- Analyzing defects with strong electron-lattice coupling
- Evaluating multiphonon emission processes
- Predicting luminescence efficiency
Dexter-Klick-Russell Rule: Determine Recombination Type
-
Identify key energies:
- En: Optical excitation energy
- EB: Crossover energy (intersection of upper and lower curves)
-
Apply the rule:
- IF En > EB: Radiative recombination occurs
- Electron recombines from upper minimum to lower curve
- Indicates relatively weak electron-lattice coupling
- IF En < EB: Nonradiative recombination occurs
- Electron crosses over to lower curve
- Reaches ground state via multiphonon emission
- Indicates strong electron-lattice coupling
- IF En > EB: Radiative recombination occurs
-
Thermal activation check:
- For nonradiative case, determine if thermal activation is required
- Nonthermal portion accomplished by tunneling
Nonradiative Recombination: Multiphonon Model
Mechanism Overview
- Strong coupling between electron eigenfunctions and lattice oscillations
- Defect level moves in band gap with atom vibrations
- Large vibration moves level into conduction band to accept electron
- Violent vibration follows capture, relaxing with multiphonon emission
- Large relaxation can convert level from upper to lower band gap half (hole trap)
Calculate Temperature-Dependent Capture Cross Section
Step 1: Determine activation energy from configuration coordinate diagram
- EB1: Activation energy for electron trapping
- EB2: Activation energy for hole trapping
Step 2: Apply capture cross section formula
σ = σ_∞ × exp(-EB / kT)
Step 3: Calculate pre-exponential factor σ_∞ (if needed)
σ_∞ = s_∞ × √(v_c × S / v_t)
Where:
- s_∞: Detailed balance factor (similar to unrelaxed trap equation)
- v_c: Number of equivalent valleys in conduction band
- v_t: Degeneracy of deep trap level
- S: Number of phonons emitted (Huang-Rhys factor)
- wr: Defect eigenfrequency of breathing mode
Luminescence Efficiency Calculation
Ratio = (En - EB) / (hω)
This ratio determines luminescence efficiency as function of electron-lattice coupling parameter A.
Output Specification
Provides:
- Recombination type (radiative or nonradiative)
- Temperature-dependent capture cross section σ
- Assessment of electron-lattice coupling strength
- Luminescence efficiency prediction
