You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention.
When the diode is reverse biased (the anode connected to a negative voltage and the cathode to a positive voltage), as shown in Fig. 2.0.6, positive holes are attracted towards the negative voltage on the anode and away from the junction.
