6. Johnny just found a box containing multiple wafers (thickness: 380 µm). On the label attached to the box, he found that the wafers are made of different materials: InP, GaP, GaAs, Ge, and Si, respectively. His advisor asked him to sort them. He randomly picked up one of them and discovered that it allows visible light to pass through under ambient light. Which wafer could it be? (A) InP (bandgap ≈ 1.27 eV) (B) GaP (bandgap ≈ 2.26 eV) (C) GaAs (bandgap ≈ 1.42 eV) (D) Ge (bandgap ≈ 0.66 eV) (E) Si (bandgap ≈ 1.12 eV)

7. Which of the following statements about free particles is correct? (A) Based on the Einstein-de Broglie relation, the particle speed can be determined by the ratio of the de Broglie angular frequency to the wavenumber. (B) Wave-particle duality becomes apparent when the particle dimension is comparable to its matter-wave wavelength. (C) The Schrödinger equation can be used to describe particles at small length scales while accounting for the effects of special relativity. (D) For free particles, both the uncertainties in momentum and position are finite, and their product has a lower bound that satisfies Heisenberg's uncertainty relation. (E) In the Schrödinger equation, the product of the group and phase velocities does not exceed the speed of light, since the speed of information propagation cannot be greater than the speed of light.

8. Which of the following statements correctly describes quantum particles under time-independent, externally applied potentials? (A) For a particle in a box, the wavefunction forms standing waves whose energy is proportional to the sum of the squares of the numbers of antinodes. (B) For particles in one-dimensional space, the wavefunction is always real rather than complex as long as the potential is finite. (C) For a harmonic oscillator, the energy difference between successive quantum states depends on the number of nodes in the wavefunction. (D) In the tunneling effect, particles experience a Dirac delta potential, and the tunneling probability is zero because the potential becomes infinite at a specific point. (E) If the potential is finite but discontinuous at some points, the derivative of the wavefunction may or may not be smooth, depending on the functional form of the potential.

6.下列何者可用於祝壽的題辭? (A)宜室宜家 (B)松柏長青 (C)福壽全歸 (D)螽斯衍慶
